You know, I'm now frankly bugged by the knowledge that there are very few Jedi that not only survive Order 66 but some (or frankly, a couple I know of) were part of the Rebel Alliance.
Mostly I'm talking bout both Qu Rahn and Rahm Kota.
...Did those two not give a damn that there is a new guy who destroyed a space station capable of destroying planets without a fricking targeting computer and is probably a strong force sensitive being?
Taking a look at both men, I do know Kota was at least around with the Rebels since day one and may have died at some point (maybe...They really need to establish something now for Kota). As for Rahn...Yeah, I'm not sure what Rahn was doing.
Only way I see it is that Kota was too busy leading reckless daring attacks until Vader had enough of that shit and killed him and Rahn was doing whatever that he didn't notice Luke till after Endor...Somehow. This or Old Ben's ghost one day just gave them the finger for even thinking bout training the boy and they pretty much ignored the poor kid into trying to learn his powers.
Personal thoughts so far?
Perhaps can shed some light on this.
Qu Rahn helped set up a refuge on Ruusan and then stayed underground rather than openly help the Rebellion, believing his main duty was to protect the Valley of the Jedi. When he was fleeing Jerec he briefly teamed up with rebels for passage so he would not have been anywhere near Luke.
As for Kota...I find with his personality and flare for suicide missions he died either right before Yavin or shortly after and never met Luke. A few other Jedi were in and around the Rebellion bu all met their ends either right before Luke met them or immediately after.
Also as to Mark Hamill's acting ability, the man was the best Joker I've ever heard and he's done a ton of voice acting that was fantastic(Firelord Ozai, the Hobgoblin, he was in SWAT KATS and dozens of other really great and different roles) so yeah, he was bland but that was one of his first roles and Luke's character is kind of like that. Also he's NOWHERE near as horrible as Hayden Christianson!
