Originally posted by DarthadiPalpatine's comment heavily implies that Luke's potential was on par with Anakin's in the context of that scene, imo. He doesn't just specify that Luke(in particular) could surpass him or w/e... He mentions that Luke could reach the true potential of his entire bloodline.
My interpretation is that Luke being the son of the chosen one (so a Skywalker) had enormous potential and can became what his father was meant to be in the sense that he can surpass the emperor which suit Vader aparently can't. The true potential of his bloodline in Luke's case might not mean Anakin level, but still more than enough for Sidious.Having Skywalker potential is a way to say enormous potential since even diluted by a generation or two, the potential would still be greater than pretty much anyone else (maybe with some odd exceptions like Rey because of the dyad)
To me, "bloodline" is just a blanket term for "Skywalkers." So the "true potential" of the Skywalker bloodline means Anakin by proxy, imo... Same with Legends, where GL commented that Luke had the potential to become what Anakin could have been.
I take the statement about Kylo being the "heir to the potential of the Skywalker line" the same basic way, tbh. /shrug
Originally posted by DarthadiMartin wasn't even aware of several major revelations from the RoS novelization after it was released. Suffice to say, I don't exactly trust his Tweets these days... Seems like the guy often doesn't really know wtf is happening.
Rey's unprecedented potential quote is from the insider. Matt Martin said that the insiders are not reviewed by the story group and are editorial like the blog section on Starwars.com. So the quote doesn't have much canon value.
Originally posted by DarthadiDon't get me wrong, power and potential are typically treated as two different things(Anakin, for example, had the *potential* to become vastly more *powerful* than he was.)
You are right that Luke's quote likely refers to potential, but it's unclear if he refers to everyone he ever met or only his students (the context was him teaching Rey), and he never met Anakin pre Mustafar anyway. ROTJ Luke is also not the most masterful force user so i don't know how good he was at sensing raw power back then.This is possibly proof of Vader losing potential after Mustafar btw.
But in some cases(like with Luke's comments about Rey and Kylo in TLJ), latent/raw power also implies massive potential that had evidently surpassed what Luke had previously encountered.
