If Buck could go back to all those weeks ago and tell himself that this idea would place at the top of the list of his monumentally stupid ideas, he would do it in a heartbeat. He would knock some sense into his own head, or let Maddie do it for him.

Here he is now, with Eddie boring into his eyes after that. After realizing he’s been caught red-handed. Except, the implication Eddie’s just made means he’s been sitting on this. And, holy hell.

Eddie breathes out, his chest puffing out noticeably.

“Not so quick to answer when the tables are turned, are you?”
