Steve will be there (although he will be mostly listening to the residents and letting them take charge of the meeting, because this is their tower, after all), as well as Sophia. And Jack tagged along with Elsa, but I don't think he really cares too much. Sam is not there, regrettably, because the 12th was the full moon. However, he would've told Wes that he'd want to hear about it later, because he's definitely interested in making sure the tower is a safe place to live, and in making a stronger community out of it.
Sophia in particular would ask for everyone's feedback with regards to how their arrival was handled, since she helps out at SI with that, and she'd want to know what could be done better. This is probably more directed at the people who've actually come through SI, since the SHIELD way was different. But any feedback helps!
