I got FWB that takes Serotonin–norepinephrine reuptake inhibitor [topped with occasional benzo after night-shift]. In 9 months didn't see much bad behaviour, nothing extreme or repetitive.

I let her be comfortable and encouraged to tell me about bad bf, very good bf that left her, bad exp in past. I stated that this is defo coming from something in past - to make her comment. Nothing.

She slipped something recently that breakup made her depressed, once short sentence and she immediately shut about it again.

Whats your exp with those kind [yes I know general rule].

Is there still potential in her to be serial killer?
