#i sincerely believe this is when he chose to become an Autobot..

[megatron-is-a-mattereel-gurl]

Honestly..the scene where Ratchet Thanks Knockout has to be one of my favorites, just because of the way Knockout reacts before saying "You're welcome."

Let's take it from Knockout's perspective.Knockout was never once genuinely thanked for what he does. He knows the words. They've just never spoken those words to him until then. So naturally, he's probably used to not hearing it, hence why he almost walks away. Then, when he actually takes it into consideration, he realizes that he was just thanked for something he did by an Autobot. Hence, why he gets so ...fantabulous-

Is that a good word for it?

About it. This is probably the first time in his history as a Decepticon he got to say the words "You're welcome."

Sorry I just really like this scene and talking about the moral implications of it.
