[ Parties are generally a bad idea, especially back in Mystic Falls, where bad things tend to happen, and the fun times always gets ruined. Damon's here to make sure that Elena stays safe, and Alaric's here with him because... Well, they haven't been spending enough time together. Enough said. ]
Here. Drink up. [ He hands Alaric a glass of whiskey. ] And stop looking like I got up this morning and ate your cat. [ Sure, a few years ago, he ate his wife -- oops -- but that's not something he'd bring up. (Not right now at least.) ] Lighten up, buddy.
