I have three questions:
1. How do I go about starting the mysterious hypnotist questline?
2. How do I get the chests in the men's bathroom in hive tower
3. If I defeat a boss the first time around (happened with the hive boss), am I locked out of seeing their "Bad end"?

Also I apologize for the amount of questions

I have gotten to around the point where you go with Evie to try to find the demon, but I haven't unlocked the tailor shop. In the wiki it says it should be shortly after getting the potion from Galiene. Is this outdated or have I just not mastered enough of the equiment?
