With X-Force in the X-Mansion, it doesn't take too long for Caliban to attack Sabretooth. Before the death-blow can be struck against the newly docile bad guy, Cable shows up and diffuses the situation. Boomer is chastised when it's found that she's been seeing Sabretooth regularly. Later, Beast has found some oddities with Shatterstar and conducts further tests while Cable and the rest of the boys head to Siberia to find out what happened to one of Xavier's underground outposts. The Mimic happened.
