Harry paced around Bones's safe house for a long time before actually showing up. It was very awkward for him because literally no one aside from maybe Neville if he came, and obviously anyone at Bones's safe house that was there, although other than Bones he hasn't really interacted with anyone. He avoided most of them and cut and run pretty quickly because awkward and still pretty angry/confused about things.
Seamus attended and probably stayed close with Susan (assuming she was there). Ernie & Megan went and likely remained with Zach who they drug there (sorry Leigh I'm saying it). If Hannah was there, Megan probably went to sit with her while Ernie avoided it like she was a disease.
Mary came, she offered up her family's castle in Scotland for them to use as a safe house since it's large enough to house many people without charms and adding extending charms could make it even better.
Penny came and so did Garrick. He offered up the ability to give out wands to those that might need a safe replacement and or a place to hide them since the shops both have basements and an above flat.
