Because it may be important for the building plot, we should probably revisit who the current X-Men are, so here's the status of my characters:
Tereza - Active Duty X-Men Roster
Wanda - X-Men candidate, but not a part of the roster yet
Natalie - Reserve, her power's specialized and not generally applicable to most missions, good for mission support
Gemmalara - Not a member, but could theoretically be counted on to defend the school at the very least
