Why not? I'm the one who told him to do that. [Luckily for Aizawa, he's not taking it as an offense to him and is treating it like Aizawa doesn't know any better.] But ah I'm so glad to hear you survived. Isn't that cool? You were beaten by my Nomu and survived!

[His thumb digs sharply into the scar, as if to search for the damage underneath the skin. He's also testing it to see if Aizawa still has any pain. Seeking for a reaction of any sort; really he just wants more to be happy about because it shows him what his Master was trying to explain to him. That sometimes losing and retreating is ok because you get to see how you grow from the experience.]

You're lucky, you know? He was bio-engineered to kill All Might.
