Not being amused was not an option for Brodie as he witnessed this exchange. Of course he would've liked to keep things between him and Jamie...Between him and Jamie but it wasn't like he shouldn't already be used to Muse and her ways.
His eyes opened widely as he heard Jamie talk about the break-in - oh, that's right, she had broken into Jamie's room, and Jamie had broken into his...and it became some kind of a chain - and the spa day. All things he hadn't seen or heard about for having been locked in his room for so long.
Brodie still had half a smirk on his face when Jamie lowered his voice and talked to him. He nodded, and smiled timidly. "That might be the better idea, yeah."
