Getting flung five years into the past is pretty much a miracle. Crash-landing on the weirdest Jedi Master he's ever had the misfortune to meet is a lot more like one extended headache for Rex, especially when he also has to contend with a brand new Force sensitivity, old friends, a Force spirit wearing a familiar face, Sith Lords, ruthless cloners, and the looming shadow of a coming war. Maybe it really would have been easier to make like Obi-Wan and find a nice, sandy planet to bury himself on.
