Well it's right before you do the guess who competition I think, and it should be in the optional objectives when it's available.
I really have no idea what I'm doing wrong then.
Tried:
- CHICK and DIK affinity (with both I was either on the Nicole & rolling with Lily or Rolling with Lily & Quinn route, that might be the problem)
- Both getting drink and not
- Completing the Santa mission, getting it but not doing it and leaving it for Tommy
- Both not kissing the girls at all and stopping after first kiss
- Helping the other girls with their sexual stuff and completely ignoring it
None of the above gave me the optional objective to return to the bowl before the start of the Guess Who competition.
