Who's Ren? Surely, a lot has happened in the 30 years between JEDI and FORCE AWAKENS. What if Ren was Luke's first apprentice -- maybe his son, but more likely his nephew (Han and Leia's eldest). Anyway, things go south and Ren turns toward the Dark Side; maybe Luke has to kill him. Kylo -- the younger brother, the second-best, the Faramir -- picks up the banner, training incomplete. He'll forever live in Ren's shadow, but will finish what he started.
