Thank Mungi!
If this takes place between #'s138 and 140, then Northstar is already a member of AF, since the entire team has already met and fought the X-Men in Calgary. I don't get why they are showing Betas and Gammas mixed in with the Alphans?...Especially if the B's and G's need more training and are not field-ready, they would not be up for the choosing.
