Yes.

Shepard considered it her lucky day, despite the current situation, because the shower was totally empty.

She hung her towel next to the door and jumped in the stall.

The hot water poured over her as she scrubbed her body of all traces of soap. Then she went over her hair to get out all the shampoo.

She was so focused on getting clean she didn't notice the door open. Or the figure move towards her.
