[Eventually Sensei will have to make Kakashi talk about it because honestly...]

[He doesn't want to. Not ever. Obito is the sort to talk even if the other person doesn't want to. If Kakashi can avoid the whole dead/not-dead conversations then he will. As it is, he's already sworn to never tell Obito the details of Rin's death.]

Maybe his face but his hair and eyes. [Those definitely remind Kakashi of Minato. His personality too seems a lot like hers.

[And there's that.]

A little. It's weird to be called 'sensei'. [And not the person that Naruto apparently expects him to be.]
