POLARIS WAS DEFINITELY IN THE TREEHAUSSSSS and she also took the opportunity to debut her new hair. So in other words, she felt pretty okay about herself. She also brought along Myrtle and hung out with her a lot because she didn't want her to feel out of place AND also gave her a single beer. I know what you're thinking, bad Po. But she figures it's ONE and Myrtle is tiny and will loosen up afterwards!
She definitely danced a lot, and drank enough to get a TINY bit tipsy but not enough to make a total ass of herself. Which she is totally worried about, mind you.
I can imagine she coaxed the girls into dancing with her (and probably the boys too) so she didn't feel alone and things and wore a silly hat and used noisemakers and was all around a fun time. She also took Teddy aside for a while when she was a little tipsy and told him about her new found crush that she is uber nervous about. So there was that. But aside from all of that, she had a really fun time. And I can imagine at midnight she went around to everyone and gave them kisses on the cheek. Because you HAVE to kiss someone at new year's, right :p?
Anyway, she probably went home as the party was winding down, or if Myrtle wanted to go because she still has to be responsible and things. So yeah. <3
