The mental image has his nose scrunching up, expression showing just how disgusting the idea is. No, thanks, crazy lady, he's happy enough with his guts inside where they belong.

"I'm able to turn into monsters or demons or whatever it is I'm fighting. Not a total copy, but I can pick up skills from them. I kinda gather malice after a fight - the souls of the monsters I've beat." Somehow. If he doesn't sound entirely sound, that's because he's going off information from Roger. Who is barely alive as it is. "Listen, my memory is basically gone, and it's a long story, but you're probably sensing that malice part. I got a thing I do to clear it out but haven't done it in a while."

As soon as this is out, he realizes just how insane it sounds. Probably stupid, too. Then again, she's the one accosting him in an alley and threatening to turn his insides into party decorations. No way in hell is he going to volunteer details on his soul forming a graveyard inside him. He's still not figured that bullshit out.
