[Mike laughs softly. Not a lot, just one chuckle that could easily be confused for another sigh by someone who doesn't know him well. Though, even if one did miss it, it's kind of hard to miss the small smile he's sporting.]

Raph, I know. I knew it the moment it happened. It's not me that needs telling, it's him. No one wants to talk about it, so I can't even apologize properly.

[Because at the end of the day Mike still sees this as his fault. And Raph probably still sees it as his.]
