Of mine, Albus, Jack, Scully, Kellen and Clarice went along to be helpful and they would all be willing volunteers. Zer0 was there as an interested but probably somewhat less than helpful observer because he's still getting used to being human himself and Robert and Henry stood in the back - Robert as something of a vaguely interested observer and Henry because he's nervy in groups. Hermann would only have come if someone dragged him along. Severus and Garrett are anti-social and did not attend. Hicks... probably would have come if Ripley was there, maybe if she didn't as well. Fenris is out of town.
Albus definitely liked Anne's idea of more social gatherings to build a bit more community. Casual ones with no pressure on people to attend but the understanding that all are welcome would be his idea.
On the security front, Clarice would have floated the idea of something along the lines of neighbourhood watch, in lieu of more professional solutions. She would point out that they have a lot of superheroes and law enforcement types here and that even a refugee patrol group, along the lines of the NYPD's auxiliary force might even be a possibility.
Kellen would have suggested perhaps a group of people who could be available for those, like himself, who have no experience with technology before they arrive. They could drop around to a new arrival and give a crash course in how to use everything. He knows there's a course provided by the ESD but most people when they arrive need to know things right away. He knows people in the tower are more than willing to do this on an adhoc basis when he arrivals ask but it'd be nice to have it a bit more organised.
