This piece of information is actually quite interesting because "Snap" Wexley never appears in Star Wars: The Last Jedi and considering that the Resistance is now small enough that the entirety of it can fit inside the Millennium Falcon, it's unlikely he got lost in the crowd. He certainly wasn't one of the pilots flying the speeder's on Crait at the end of the film, and considering how few pilots were left, they certainly could have used him. We would have written off "Snap" as one of the many Resistance members who died over the course of the last episode, but it seems that's not the case. Will Grunberg's character appear in Star Wars: Episode IX as if he was part of the surviving Resistance that we just never saw? If not, and he was actually elsewhere, how did he get away and why didn't he respond to Leia's distress call?
