Spoilers: A group of X-Men (Rogue, Storm, Beast, Old Man Logan, Emma Frost, Young Beast, Magneto, Forge) discusses the last Terrigen Mist cloud. Beast reveals that he's out of time, and mutants only have 2 weeks before the cloud spreads across the whole planet. His only options are to leave the planet or die. Emma reveals that she has had a back-up plan in the past 8 months in case Storm's plan of peaceful co-existence fails. Magneto says to fight, refusing the mutants to be gassed. Beast is against this, with first-hand experience on the Inhumans and what they're capable of. Emma next outlines her plan to systematically take out the key Inhuman threats, starting with Karnak, who knows the truce will fail from his ability to sense weaknesses. Logan reminds Emma of the threat Lockjaw presents in jumping Inhumans around. They have a vote. Rogue votes no. Forge abstains. The rest are pro-attacking. Beast is outraged and walks out to warn the Inhumans, but Storm blasts Beast with a lightning bolt, revealing she was a part of Emma and Magneto's plan the whole time.
Later, at Black Bolt's club, a mysterious VIP wants to speak to him, whilst new performer 'Lady Shine' has been very successful. Emma is in the club, chatting with Black Bolt. She invites 'Lady Shine' in the room and declares the truce is over. Lady Shine pulls a gun out on Black Bolt, and he uses his power, saying "Don't". Lady Shine is actually Dazzler. Emma punches Black Bolt in the throat with her diamond form "for Cyclops" and Dazzler redirects the energy stored into Black Bolt, leaving him down.
Emma sends a mutant on Karnak's way. The mutant visiting Karnak is actually Jean Grey, and she's keeping him distracted in a time loop, replaying conversations six times over. Gorgon and Crystal are helping rescue a Russian mutant in Chechnya just before the cloud arrives. The Russian rescued mutant is actually Magneto, and he destroys the ship and holds everyone on board in metal, claiming he is the only one who saves mutants. Cut to Ms Marvel walking Lockjaw, when the dog suddenly disappears whilst she is on the phone. Fantomex knocks out Lockjaw with some drug.
At New Attilan, Medusa and Johnny Storm prepare new children to undergo terrigenesis until Torch notices something coming. Johnny flames on, Medusa wants to maintain their truce and talk, but if they want a fight, they will fight. The X-Men then dash towards New Attilan, including Storm, Colossus, Nightcrawler, Old Man Logan, Magik, Iceman, Magneto, Psylocke, Sabretooth, Monet, Archangel, Sunfire, Strong Guy, Youn Cyclops, Young Angel, Young Iceman and Oya.
