Wolverine while not enthusiastic about the Phoenix coming back but it could mean the return of Jean. Even if Jean coming back wasn't a possibility he sure as hell wasn't going to let Tony Fucking Stark steal a child from her family. That is why he pledged the support of the Jean Grey School for Higher Learning to Utopia
Wolverine made everyone at the school aware of the situation and anyone who wanted to volunteer was welcome.

Tony was flying in the air above the battlefield like a coward. Wolverine grabbed Nightcrawler and they went to Colossus. Wolverine climbed into Colossus' hand and Nightcrawler jumped on Wolverine's back. "Kurt drop me above Iron Man when I say." Colossus threw the pair straight at Iron Man. Wolverine waited for Iron Man to turn and fire at them and gave Kurt the order. Before Iron Man could react to them disappearing Wolverine claws were tearing into the back of his armor. The damaged Iron Man fell to the ground on top of Red Hulk. Wolverine landed behind Deadpool.

Talon was under orders to monitor Avengers vs X-Men, she was put in charge of a squad of Mandroids and a Boeing C-17 Globemaster III nicknamed The Bus. Talon strapped on her S.H.I.E.L.D. Flight Pack just in case. "Do not interfere unless they attempt expand their fight past Utopia's borders. If the fight expands, do not fire directly at them unless they attack."

Tigra was on a mission for the Avengers West Coast with US Agent, John Walker. John was all for the proposed Superhuman Registration Act. She was against it but she wasn't one to advertise her political leanings, especially on a mission. John spent the entire ride in the Quinjet talking about it. She wanted nothing more than to sleep on the ride but he just wouldn't shut up.
