The ones that I can come up with right now (as of this moment) are;
- Lenny
- Edmund
- Dulrig (but only if you asked him to help fix the gloryhole, I think)
- Random Man with pink panties
- Random Man who's very sensitive and loves showing off
- Ste (one-time only, I assume. When you check the gloryhole with him first time)
- Minotaur
- Ratkin
I may have missed some?
