Bishop Cosplay
Iceman, Sunspot, Blink, and Warpath fight the Sentinels while Shadowcat and Bishop run into a closet somewhere. Bishop lies down and Kitty massages his temples and sends his consciousness into the past. The others buy time with their lives. A Sentinel grabs Sunspot's neck, Iceman's head is cut off and crushed, Blink is impaled and Warpath is torn to pieces. When the Sentinel breaks through the cupboard and blows up the fire, everything disappears. The past has been changed.
