[Right... Akechi's past. It's like a memory of a memory at best. He much prefers hearing it from Akechi himself.]

... That was still before you came here.

[Maybe he wasn't speaking clearly enough... but, every time he tries to start talking about it, he can't quite get the words out.

Ever since I got here, all I've done is screw up. You forgave me for some stupid reason, but now I've hurt... someone who thought of me as a friend. Someone who I would've thought of as one, if I could. [It's not like he can really care.]

I'm not cut out for this. Being around people. Being 'nice.' I figured I should at least let you know before I skip town so they don't send people looking for me.

[Maybe he'll find some place underground, like before. He won't have to bother anyone there.]
