Marvel Comics X-Men One Man's Worth, Part 2

S4, E5: Failing to stop the assassination of Xavier, Storm convinces Wolverine they must help Shard and Bishop until they succeed in ensuring Xavier's existence. They travel forward to the future but now the past has changed enough so that Forge's time travel machine has never been tested- not to mention that Forge has no idea who these four time travelers are! Will Nimrod succeed in stopping them? Will Forge's machine function... if he even allows them to use it? Or will this band of time travelers fail to save Xavier for a second time?
