SLIM has been SNACKING.
Hittin' them BROTEIN shakes hard.
Duggan's just being playful and using adult language. As adult's often do.
I wouldn't be mad at Kate's inclusion. I would enjoy seeing her play off the Avenger folk on that cover.
Additionally, I would ADORE it if ALL the X-rep is female. All the best X-Men are women. It would be nice to see Tempo on the team, as well.
