Baelfire found Henry. He stuck with him. Attacked Gremlins with a hot dog skewer but his main priority was you know...getting out with his sonbro.
Albus had Helena and he went into Dad mode. He found Luna (and Credence? I'M NOT SURE IF HE WAS THERE) and asked her to get Helena home but then found out Luna can't apparate so he apparated his kids out. HE DID HOWEVER come back to help. Probably was focused on trying to usher children to safety?
Charlie has been anticipating something like this happening so he just went into Wizard fight mode.
