At the Avengers academy, Juston is attempting some work on his sentinel when he is interrupted by X-23. She is curious as to why he would possess something built to destroy mutants. Juston explains that it has been reprogrammed primarily to protect himself, and shouldn't be a threat. Except maybe verbally.
X then goes to talk to Dr. Pym who explains to her how the Phoenix powered X-Men are attempting to irradicate hunger and violence from the planet, and that if she decided to leave to help them that he would be understanding. She chooses to stay, regardless.
The White Queen suddenly arrives, triggering the sentinel's mutant hunting weapons, but is no match for the Phoenix power. Juston convinces her not to destroy it, but instead wishes to erase it's central processing unit. Juston insists that would be like killing a living being, reminding X-23 of her childhood pet. Giant-man then rallies the junior Avengers together in defence of Juston and his sentinel.
