"He is always upset. The more you wait, the worse it will get." Knock Out moves to check on Rung's shoulder. If he was there he might as well make himself look busy in case someone else decided to interrupt them and ask what where they talking about.

"Listen, you might get yourselves in a lot of trouble, if you decide to give this mess a try you need to be discrete about it." Again, it's not like he cares, okay? Decepticons are not allowed to care. He just doesn't want to have to clean the mess if someone kills you.
