I also felt she looked a bit awkward.

But I think it's all ok. She had had her letter from her BF and Chris was a bit drunk and emotional and probably just being more lovey than she felt like being in the wake of receiving her letter from the BF who maybe she hadn't been thinking about so much recently.

Their friendship is strong enough and Chris is mature and sensitive enough for them to sort it out if she had an issue. She does not need a mangina public getting defensive of her, she is confident enough to cope with it.

TL;DR even if she was momentarily uncomfortable, it is not the end of the world. People always come across strongly after a few drinks, does not mean you become uncomfortable around them. And even if you do, that is what we use our mouths for; conversations and expressing our feelings and coming to understand each other.
