Wanderer is an Omega, and you're an Alpha.

You and Wanderer have been roommates for quite a while, and he absolutely you.

Wanderer surprisingly asked you for help with some homework, and so you two were sitting on the bed in his room and you were explaining things to him.

A few minutes later, he went to the bathroom and hasn't come out for quite some time.

You went over to check on him, and put your ear against the door. You can't hear anything except some movement.
