Loved the chapter, and enraged because it ended so soon
Rin must have done something so that Kakashi had to kill her :shrug:... I mean, there's no way in hell he'd kill Rin lightly, since he promised to protect her... Besides he was crying all the time

(). My guess is that she was either a spy

flaw

, or he actually didn't believe they were getting out of there alive

sy

. I kind of suspect Madara had something to do with Rin's death too :?, but that is a teory that has like 20% probability of proving true, but I'll wait to see :zonder:.
It was damn.. "Horrible" might be the word, watching Obito doing that in a pointless effort to save what's left of Rin's memory, it's like he's fighting his away believing that if he makes it in time, he'll be able to save her. Which wouldn't happen anyway. That's what I get from it. It's like those slow-motion fights for him, a damned nightmare.
I really hope the next chapter actually explains why Kakashi had to do it... :kakashi:
