Lena's Attendees. Jaina :: came to show her support for Hope. She washed off the engine grease and cleaned up nice like you do when your mom is Princess Leia.
Josie :: also there to support Hope and be only a little jealous that she has another year of high school. She also dressed up a bit. Most of her time was probably spent with Hope and/or Lizzie, but she did mingle, too.
MJ :: this is really not MJs scene, but she did show up for Hope and probably mostly hung around her and/or Peter and probably also Nico a bit. She wore a nice dress for the occasion.
Peter :: I think that per DM discussions, he was there as Lizzie's sort of date. He doesn't have a job yet and may have showed up in his Narnian High King garb unless Lizzie got him something more appropriate LOL
Rose :: Hope told Rose about the party after she made her post about grad parties, so of course Rose came to party with her friend and eat a LOT of food. She's not working yet, but managed to find a simple black dress.
Thea :: She's chatted with Hope a few times and Hope invited her to the party, so she stopped by to wish her and the other grads there well and she also would have kept an eye on Nico and kept him company if he wanted for part of the night. She's in a nice pantsuit.
