Jack Reacher

You assured Jack that you didn't need anyone to watch your back while you took a shower. You trusted him to go to the vending machine just outside and down the hall to get the both of you some snacks, and since you were all alone, you could finally loosen up a little, singing in the shower and not caring just how loud you could get.
Jack returned with the snacks, taking his time as he barricaded the door again, hearing your voice behind the bathroom door, unable to help himself as he stepped closer to listen to you sing.
