hehe, when did Luke get his X-Wing back ?
I forgot that he parked it on Cloud City (now off-limits for Rebels), but flying it later to Tatooine and Dagobah ... (*
as for the Prequels: just keep the Kids out of the story, we didn't see baby Obi-Wan or Han (we had luck!) neither!
*) and without R2 "Autopilot"ing it, who returned it to him ?
