Warning: SPOILERS for Uncanny X-Men #21
There has been a lot going on with the X-Men as of late, and to say they are in trouble is an understatement. General Callahan has a pure hatred for mutants, and is doing everything he can to wipe them out. He created a vaccine that depowered a generation of mutants, and has sent Sentinels out to hunt the rest of them down. And Wolverine just helped lower their number by one.
Logan has always been a wild card, and had killed his fellow mutants in the past, but this time he did it out of humanity -- because one of their own was having their powers used against them all. Velocidad, AKA Gabriel Cohuelo, who was one of the teenagers of Generation Hope, has super-speed powers. However, whenever he uses them, he grows older at an alarming rate. This has led him to do some things in his life that he might regret, all because he wants to live it to the fullest before he dies.
Wolverine is in the process of fighting off multiple soldiers in Uncanny X-Men #21 when he smells... something. Sniffing it out leads him to a small, dark room where Logan discovers Velocidad, in intensely rough shape. Thanks to the malevolence of the X-Men's enemies, Velocidad has been aged to the point where he is almost unrecognizable. Helping in that disguise is the result of his connection to a piece of Warlock, a techno-organic alien now weaponized for this dark purpose. Gabriel is obviously near death, and there is a good reason for it.
Velocidad confesses to Wolverine that he has been trapped in this state for years, which confuses Wolverine, having crossed paths with the mutant just a few months previous. The timeline hasn't been fractured--but the truth is much, much worse. General Callahan has been forcing Velocidad to grow new Warlock specimens using his super-speed mutation, explaining why he has aged so much so quickly. Warlocks usually take hundreds of years to reach maturity, but not with Velocidad's powers. It turns out super-speed isn't always a gift, after all.
Wolverine decides to help the former hero Gabriel out the only way he can. After offering to rescue him, Gabriel admits that he won't survive. "They've been keeping me alive. Just tell Blindfold I'm sorry I didn't believe her. Tell her she was right." Those are Velocidad's final words as Wolverine decides to help by putting Gabriel out of his misery the best way he knows how - with a SNIKT.
