I’m shocked, tell me it’s not true please
If you revisit the clinic frequently, Iosevka has a noticeable personality shift at one point. She gets replaced by a Choir member impersonating her, who is running bizarre experiments. When you get into the back of the clinic, that's what you find.
Tap for spoiler
In addition to the real Iosevka being turned into a kindred, the imposter will also transform any civilians you direct to her. This can be useful with the guy in the woods who is actually a beast in disguise and will kill everyone in the church if you send him there. Sending him to the clinic is easier than fighting him too.
