Fallout 4 Companions Headcanon

Danse doesn’t know that women have periods. He never thought much whenever female soldiers would go use to bathroom for extended periods of time. A bit confused, but they have their own personal duties.

Hancock and Preston know /of/ women having periods, but no actual knowledge.

Nick, MacCready and Deacon know an average amount of knowledge on this subject.
