*Bellatrix loves weddings. Not what one might expect, considering her own less-than-fairytale marriage, her naked contempt for her husband and most men; in truth there are probably expensive cauldrons that are more romantic than she is. Still, something about the ceremonial pomp of everything, the white dress, the promising to love-and-honor. . . she may have no patience for finer feelings but duty to family and noble tradition resonate with her, deeply. It was that, more than any particular liking for any of the individuals involved, that had her sniffling through the ceremony, weeping, even, and that sentimentality lingered long enough for her to take a turn around the dance floor with Rodolphus after only minimal coaxing.

But now he's off making nice with the Higgses and she knows herself better than to even try, so she's strolling the reception with champagne flute firmly in hand, her tears long since wiped away, looking for someone to bother. And that someone appears, in the green-robed guise of someone on the bride's side, and she quickens her pace. Her walk doesn't betray her intoxication in the slightest--tipsy and in high heels is practically her default state--but her crooked smile does, as she plunks down next to Jyoti.*

Lovely wedding.

I assume you're with the bride.
