I noticed that, but Claire already felt safe enough around Marten to drink a little bit if you remember the wedding, so maybe she'll drink some of the secret bourbon. From what we've seen she doesn't drink normally, so she probably doesn't have much tolerance. So lap barfing might still be a possibility.
I have no idea why I wrote all this, because that lap barfing reference was just a joke.
And yes, Faye was absolutely great in her happy moments ("I like this bar!").
Hedgie: If you remember Clinton's reaction, I'd say it's pretty sure that Claire isn't the person to drink. Definitely not in a bar. Maybe she's more willing at Marten and Faye's place.
Edit: And I just realised how incredibly creepy that sounds. It sounds like I would want Claire to get drunk and do something stupid. Please note that that is not what I meant.
