Tish's Luke is, obviously, there. Out of everyone living in the temple he probably knows the least about the Jedi but he'd help out in any way he could. His teachers just may have to tell him where he's needed.
He's the only one who might be involved but... a number of my others probably went.
Adam and Dean were talking about this the other day which means that Adam definitely went with Dean. It's a brother bonding event or something. Billy is 14 which means he loves Star Wars and he would've gone either with Courtney and anyone else from the house or on his own. Ray is a HUGE nerd and he loves Star Wars so much. He was definitely there maybe with Constantine if his boyfriend agreed to come. Tommy went, too. He usually avoids things but this seemed interesting.
The rest of mine would've only really gone if someone they knew was going. Bill is interested but he's also kinda depressed so going seems like too much unless his boyfriends or the Losers (including Will and El) decide they want to go.
