If Knock Out knew what was going on inside Thudercracker's processor he would have smiled sadly at him. He also lost faith in the cause long time ago, long before he changed sides and decided to join the autobot's team. But staying with Megatron was safer, in a way. He knew what happened to those who betrayed him, or just thought of it. He saw it first hand with Starscream and Dreadwing.

However, Knock Out also noticed the growing madness of his former master and how useless the cause had become. Like Thundercracker, he was tired of follow order, tired of not being given any respect or even considered anything else but a pawn. He was, more than anything, a practical mech. There was no point on following a path that lead to nowhere. But that was a story for another day.

Once the seeker arrived, he found Knock Out with his arms crossed, looking not all that amused. "You are late. What took you so long?"
