How does Leo even do that? Is there some sort of special Big Brother Ninja skill that gives him the ability to have pitch perfect timing? At best it's uncanny, at worse...creepy as all get out.

Mike barely has time to wince at the slamming of the window before Raph lunges. He has no idea what they're talking about, but judging by how quickly Leo lowers to Raph's level, it's something serious that's been festering.

Helplessly he watches as the event unfolds before him, unable to move due to a mixture of confusion and being caught off guard. That is, of course, until Leonardo uses "shell" in the place of profanity. There's something so ridiculous about that, that it manages to break Mike free from his passive spectating. He slides down off the couch and attempts to move between the feuding brothers.

"Guys guys guys! Hey, come on...back to your corners."

Isn't Karai the girl that had a beef with Leo?
