Overview

Sonia is the research scientist at the University Research Lab in the Present era. Her personal route alternates automatic lab scenes with three selectable heart-to-hearts. This guide gives the unlock order and best relationship replies while leaving the wider story's discoveries unexplained.

Quick Stats and Availability

Detail Current value
Age 27
Era / alignment Present / Neutral
Location Research Lab, University Campus
Schedule 9 AM–5 PM every day
Favorite stats Intelligence 45, Perception 50, Technology 35
Special relationship skill Nano-Engineering
Favorite gift Flowers
Main personal-route gate Story Beat 11 completed; Acquaintance
Listed relationship rewards are base values. Favorite stats add bonuses when their thresholds are met, and the special relationship skill doubles the adjusted base before the shared random roll. Equipment, buffs and alignment can further change the final reward. Raising affection does not replace quest flags or earlier heart-to-hearts.
The Research Discussion reward is a fixed direct affection award, as marked below. Sonia's special skill is a relationship bonus; it is not a lesson taught by her ordinary menu.

Relationship Actions

Action Requirements Cost Reward / limit
Talk to Sonia Stranger or higher 15 minutes 1 base; four daily
Allow Testing Stranger through Acquaintance 45 minutes; 20 Energy; 20 Calm 4 base; three daily
Research Discussion Known; Communication 30 30 minutes Intelligence +1 and 8 direct affection; once
Give Flowers Acquaintance 15 minutes; one Flowers 10 base at Acquaintance/Friend, 15 from Close Friend; twice daily
Allow Testing disappears once Sonia reaches Friend. Keep ordinary Flowers in your consumable inventory for the dedicated Give Flowers action. The menu's generic flower estimate is lower than the current handler's actual stage-dependent reward shown above.
  1. Visit during lab hours. Use Talk and Allow Testing for early affection, and claim Research Discussion when Known and Communication 30 are reached.
  2. Complete the early main-story research sequence through Story Beat 11. Return to the lab at Acquaintance to start The Unfiled Variable.
  3. Follow the nine-step personal sequence below. Re-enter the lab when an automatic scene is due; choose the three heart-to-hearts from Sonia's menu.
  4. Use Flowers as needed after Acquaintance. Optional dates give more affection but do not replace any route milestone.
  5. After No Control Group, reach 600 affection for the repeatable paid Biobot Transfer action.

Personal Route Order

The six ordinary scenes in this sequence each occur once automatically at the lab when their gates are satisfied. Their quoted totals combine completion and best-choice base rewards. The three heart-to-hearts are actions and must be selected explicitly.
Step Stage and preceding milestones Time window Best reply Base reward
The Unfiled Variable Acquaintance; Story Beat 11 completed 9 AM–5 PM Caring 8 +5 =13
An Hour Without Data Acquaintance; The Unfiled Variable completed 9 AM–4 PM Funny 10 +5 =15
Outside the Protocol Friend; An Hour Without Data completed 11 AM–3 PM Heart-to-heart below 50 maximum
Failed Calibration Friend; An Hour Without Data and Outside the Protocol completed 9 AM–4 PM Caring 12 +5 =17
Personal Results Friend; Failed Calibration completed 9 AM–5 PM Flirty 12 +5 =17
Stay Without a Reason Close Friend; Personal Results and Outside the Protocol completed noon–3 PM Heart-to-heart below 60 maximum
A Forecast for Two Close Friend; Personal Results and Stay Without a Reason completed 9 AM–4 PM Caring 14 +5 =19
A Result Worth Keeping Crush; A Forecast for Two completed 9 AM–5 PM Flirty 15 +5 =20
No Control Group Crush; A Result Worth Keeping and Stay Without a Reason completed 2–4 PM Heart-to-heart below 77 maximum


No Control Group explicitly checks the preceding heart-to-heart; following this sequence also completes the first one. Affection alone cannot skip the plot gates. The automatic scenes have no separately configured action time, money or Energy cost.

Heart-to-Heart Answers

Each of Sonia's three heart-to-hearts costs 60 minutes and 15 Energy, and can be completed once. They have no paid-version gate. The time windows and earlier plot requirements are listed in the route table.

Outside the Protocol

Round Highest base-point choice Base points
1 You don't have to perform this correctly. Just be here with me. 8
2 People are uncertain, but that doesn't make every uncertain thing dangerous. 9
3 Being refused can hurt. Never asking can become its own kind of hurt. 10
4 I'll note that dignity was the first component to roll under the cabinet. 11
5 I'll stay. You never needed to earn the time. 12


Stay Without a Reason

Round Highest base-point choice Base points
1 I volunteer to prevent the second cup from invalidating your sample size. 10
2 Then I should visit often enough to reward that attention. 11
3 I miss you too, especially when I have no excuse to come here. 12
4 Then let your wanting be enough. 13
5 Wanting me here is reason enough. 14


No Control Group

Round Highest base-point choice Base points
1 I promise not to alert the peer-review board. 13
2 We don't need another timeline to value this one. 14
3 I choose it too, with everything we still cannot predict. 15
4 I want you to kiss me, Sonia. 17
5 Then kiss me again as personally as you like. 18


Heart-to-heart choice points accumulate and use the shared relationship calculation at completion. The listed points are base values, not guaranteed final affection gains.
The maximum choice totals are 50, 60 and 77 base affection, respectively. No extra completion affection is configured. The player's Romantic skill adds a fixed 25 final affection after the ordinary calculation, rather than adding 25 to the base total.
No Control Group's last round records 5 Sonia NPC intimacy experience in Kissing. The two earlier conversations do not configure NPC intimacy experience. None of the three gives player Erotic experience.

Optional Dates

Both dates are one-time higher-power paid content. They are available from Sonia's lab menu during the windows below and do not block her main route.
Date Requirements Window Cost Best choices and reward
Boardwalk Daytime Date Friend; Outside the Protocol completed; Diane's boardwalk built 11 AM–3 PM 60 minutes; 30 Energy; $50 Caring → Funny → Flirty: 5 +5 +5 choices and 10 completion =25 base
Farmers Market Date Close Friend; Personal Results and Stay Without a Reason completed noon–4 PM 120 minutes; 35 Energy; $50 Caring → Flirty → Funny: 5 +5 +5 choices and 10 completion =25 base
On the boardwalk, choose “We can walk slow. Take your readings…”, then “Citation: 'Sonia, Boardwalk, field observation…'”, then “Then start small. Walk the boardwalk…”. At the market, choose “People return because they remember how they were treated…”, then “Choose what you want…”, then “I'll prepare a rigorous schedule…”.
These dates configure no NPC intimacy or player Erotic experience. Their conversation rewards use the normal plot relationship calculation; they are not heart-to-hearts with the Romantic completion bonus.

Research Quest Crossovers

Two independent automatic lab events can supplement the route. Both run 9 AM–5 PM and occur once.
Event Gate Best reply Affection
Agricultural Research Discussion King Graham's Dragon Food Crisis completed; Sonia Known “Someone is counting on me to find a way to keep people fed.” 10 completion +5 choice =15 base
The Encrypted Signal Story Beat 4 completed; Sonia Friend Caring or Flirty 5 completion +3 choice =8 base
The agricultural discussion is also the completion gate for travel to the Farmers Market. Its completion is separate from the optional Farmers Market Date. The dialogue choices do not prevent completing either crossover event.
Early main-story visits also award Sonia 10 base at Beat 1, 5 at Beat 2, 15 at Beat 4 and 5 at Beat 11. Beat 1 starts at the lab during lab hours. Beat 2 continues at the Uptown Beach, 8 AM–6 PM, after Beat 1. Beat 4 returns to the lab after Beat 3 and requires Acquaintance. Beat 11 follows Beat 10 through the lab's research story action. This lists progression gates without revealing research findings.

Biobot Transfer

After No Control Group, 600 affection unlocks this lab action during Sonia's 9 AM–5 PM schedule. It requires the paid version, takes 45 minutes and 40 Energy, and gives 50 base affection once per day through Sonia's video-action handler.
The current scene has no configured NPC intimacy experience or player Erotic experience, and no additional heart-to-heart choices. Its ordinary affection reward is calculated separately from watching the scene. Sonia has no current affection-unlocked portrait gallery entries or worker recruitment route.

Troubleshooting

  • Sonia is absent: visit the lab between 9 AM and 5 PM.
  • Testing disappeared: it ends after Acquaintance; use Talk and Flowers instead.
  • Flowers give more than the old guide says: the current handler awards 10 or 15 base according to stage.
  • The personal route does not start: complete Story Beat 11 and reach Acquaintance.
  • The next automatic scene does not trigger: check its narrower time window and the preceding heart-to-heart, then revisit the lab.
  • A heart-to-heart is missing: its specific plot milestone, stage and time window all apply; completed ones disappear.
  • Boardwalk date is missing: build Diane's boardwalk and finish Outside the Protocol, with Friend, higher-power paid access and its daytime window.
  • Market travel is missing: finish Agricultural Research Discussion; the romantic date alone is not the travel unlock.
  • Biobot Transfer is missing: both 600 affection and No Control Group are required, plus paid access.

Credits and Current Scope

Verified against Sonia's current action handlers, heart-to-heart definitions, personal route, optional dates, quest registry, story gates, shared rewards and video completion. The existing portrait and house style are preserved; major story discoveries and unreleased story continuation are omitted.
