2 Works in X-Men Reverse Bang
Charles plans to have a nice quiet (Fraternity free) Sunday, but instead he ends up helping his brother to look for his lost Gunsmith.
When Wesley finds out what's been happening in Charles's life, he stops tracking down the last few members of the Fraternity and comes home. There's no way Wesley's going to let Charles risk his life without backup. Takes place in the XMFC chronology (with Wesley's experiences in the Fraternity moved into the 1960s to match).
