OOC: Why wouldn't they use the fake last names? Won't there still be normal people, so they have to keep their identities secret?
OOC: Raven will still be Alice Wilson because Raven Fury's still dead.
I assumed Eli and Penny used Stark at their school, so since they're going back, they don't need to hide.
Coulson isn't a recognizable name, June and Phil Jr. should be safe.
Wilson isn't either, Conrad would be safe.
Hill is a common last name, Nova would be safe.
Rogers is a common last name and Michael is an even more common first name, and Nancy I don't think has the same level of fame as the boys, so Mike and Nancy would be relatively safe.
Banner is really only a recognizable name in science, Ross is dealt with and it's not like Bruce is recognizable when he's the Hulk so Hope is safe.
Jay and Evelyn may or may not need fake names depending on how Olivia will continue to play the Barton thing
Gordon and Thora may need names too, demigods might just be a little too much to handle, even for NYC.
Besides, it is still a high density superhero area, and some people are well known both as regular people and superheroes or are virtually unknown because their secrets are so secure so it doesn't matter.
