i'm on RLC since a few months so there are much former RLC tenant that i've never seen, but now except the new Nikki (and Jenny who immitates her) the only girl a little bit shy on the bathroom is Suzanne with her bathrobe.
All the other people act normally in the bathtoom. Sometimes Butch from Carla and Sabrina is very quick in the bathroom but i think it's more for psychologicals reason(a girl body in a man mind).
So i think they have some have instructions to be as naturals as possible in the bathroom and dont hide.
Even Dasha and Demid who hide for sex, dont hide in the bathroom.
Nikky is there just because she has beenn called in an emergency to avoid Jenny staying all day long alone in the appartment. She doesnt care to be fired
Excuse my poor english
