After talking to 5 characters (Linden, Erika, Blue, Grant, Simon), they all mention going to a community meeting and clue its location. The meeting location is CIRCLE DANCE, a statue located on the South Walk. Inputting this promo code gets the solver a new 6th match option.
The secret match (Three Tinfoil) mentions being a prankster and a hater clueing more obviously what you need to find next. Then he gives the solver a diagram that needs to be filled in with a red flag, special interest and zodiac sign for every character.
After filling out the diagram and indexing into the two traits by the position of the Zodiac sign in the conventional order, solvers obtain the following data:
| Character | Red flag | Special Interest | Zodiac Sign and position | Extracted Letters |
|---|---|---|---|---|
| Linden | LIAR | SONGWRITER | Gemini (3) | AN |
| Erika | GHOSTER | MEME LORD | Cancer (4), Gemini (3) | SM |
| Blue | CHEATER | STARGAZER | Cancer (4) | AR |
| Grant | GASLIGHTER | AUDIOPHILE | Aries (1) | GA |
| Simon | CONTROL FREAK | NUMISMATIST | Sagittarius (9) | RI |
| Tinfoil | HATER | PRANKSTER | Gemini (3) | TA |
Reading out the extracted letters gives ANS MARGARITA, so the answer is MARGARITA.
