(after reading Manga 628)
bam, just like i thought!! Kakashi and Obito are gonna have a little 1 on 1 time in the other dimension to talk to each other. ever since Rin's Death Story was incomplete, i knew at some point, they had to take a pause somewhere mid-battle to convo it up and reveal why Kakashi killed Rin.
so, looks like that's what the next chapter or two is gonna be. flashback story time, yay!!
