late, but if you want to thread...
Polyxena showed up late, which had been a calculated move on her part. She actually hadn't gone to the movie at all, which had been another calculated move.
She went to the party, though. She'd gotten back in town that day, mainly because she knew that the party would be happening and she knew she'd have to meet Achilles at some point. She figured the bigger and more dramatic, the better.
So she slipped into the party. She was wearing a short, black dress with lacy cutouts that showed perhaps a bit too much skin. But that was also the point, at least a little bit.
