"Once a Parent" (Uncanny X-Men)

The sounds surprise him--he recognizes those voices. The X-Men burst through the mansion's door into a shocking scene: confused students being gathered, Guardian flying away, holding a screaming Annie and Carter.

Bobby's shout comes before he can move, but it isn't necessary, because he would have done this anyway.

He streaks through the air, all his being focused on the red and white suit of Alpha Flight's leader, previous friendships thrown aside by his most important rule: Nobody separates parent and child against their will, not while Northstar has strength left in his body.

"Pour ma petite. Pour Joanne."
