GIDEON: will be doing everything he can to help in the vaults and wherever needs it. he'll definitely want to go investigate the sounds from the mountains and he thinks he's the best one to do it because he has no super-immediate family depending on him. and he's reckless like that so he'd so volunteer.
ANDROMEDA: is in the vaults since she volunteered. she didn't want to separate edgar and sally or james and lily so she let them stay at moody's. plus, ted's at the vaults so it's a win-win situation for all of them. when she's not being useful, she'll be staying with ted. she'll also be talking to narcissa and making sure dora checks in with her often.
WILLIAM: is at moody's with the sick. snakes killing him, other things killing him, sedation, etc. if he sees the fire, he'll think that's coming for him as well. keeping him sedated is the best thing possible.
LYSANDER: is also at moody's because he's got a broken collarbone and arm. the bones are healed/healing by now, i imagine, but he's still recovering his strength. plus, lorcan's there and he's not leaving his brother. he's got emmy with him because he's NOT LEAVING HER ANYWHERE!
