Jamie/Lily
As predictable, Jamie was spending his time going from cousin to cousin. He might want to support Lily, but had no interest in interacting with her 'friends'. In fact, he was sure that she didn't even know some of this people, a fact he didn't feel he need to prove or disprove by talking to them, but he did want to talk to his sister.
He waited for her to be free and then with to her. Jamie kissed her cheek. "Well, congratulations. The record sounds great and I'm sure it'll be a great success." Of course their last name would ensure that, but it helped that it was actually good.
"Otherwise, how are you doing? Still sober enough to talk to your oldest brother or would you rather that I let you party?" he asked, really okay with either option. It was her night after all.
