Ok... I only commented on their height during the attack on Konoha, so not really sure what you're replying to here.
Obviously he didn't die. And why can't he be as tall as Minato at 14? Why the hell are we even debating his height as a plot hole? Are the Obito detractors really that desperate? Growing tall during puberty is not a plot hole.And why is this even being debated, it has already been established that kakashi became chuunin at age 6 and jounin at age 13 (nearly the same as itachi), also the fact that he is 26 at the start of the show means obito died at 13 and the naruto's birth was 1 year later.
