The use of his first name prompts Coop to give her a dirty look, not that it lasts long because he's knocking her hand away from his side but if he's honest, he doesn't hated. He's never hated it, not really, 'Coop' is just a nickname that had been given to him in high school and had stuck. He's just never really bothered to tell anyone that calling him 'Shea' is fine with him, but it always makes it mean something a little more when people actually do.

Granted, Keira's just giving him shit so it probably means absolutely nothing to her. It doesn't matter, though, she can keep doing it because he kind of likes the way it sounds coming from her.

"Heartbroken, huh?" He rolls his eyes playfully as he knocks her hand away again before reaching for the bottle of vodka he'd brought. "Well, you can tell her that she can come here and drown her sorrows with some booze. The three of us, how about that? It'll totally be the best Christmas Eve either of you will ever have."
