You should've known there was something going on between Price and Shepherd. It was an excuse every time Shepherd called Price in to "discuss" a mission.

You were suspicious, just from the way Price left Shepherd's office. That's why you waited until Price went into Shepherd's office and peeked in.

Price had pulled Shepherd by the collar over the desk, their foreheads nearly touching. Price was too close, his lips almost touching Shepherd's.

"John." Shepherd just says, eyes narrowed.
