I think they just added that dynamic for comedic purposes. I just take it as a bit of competition between the two brainiacs and nothing more. They were both trying to be the smartest. I don't hold any grudge against Rockwell but yes he was being arrogant in trying to be superior. I can understand why you'd interpret it as being mean-spirited but I don't think he actually disliked Donnie. Although, you never know, their first fight in 'Monkey Brains' and Rockwell winning could have something to do with it. It just didn't bother me but I'd probably hate him if he was a real person.

It's just that the first words out of his mouth in that episode is antagonizing Donnie. At least he's shown in the second part to be a jerk with a heart of gold.

You mean the "And what pray tell are you staring at, boy?"
This isn't the first incarnation to give Donnie an intellectual rival, but hopefully it won't be a 'who's IQ is higher' pissing contest every time they meet.

For all who are wondering why KSP still relies on his Irma cover, maybe he just likes to look like a Girl? Mayyybe deep down in his huge brain he wishes to be female so he lifes out his dream with his Robot suit lol.

Personally i don't think he is dead yet, he seems to be rather sturdy and got a lot of Stamina for a Little brain. I think he will reappear with more cybernetic parts and kick those Shell-Heads at least a Little xD(KSP is really the only Kraang i can stand as he has an own personality and is so much like OT Krang ;A;)

The rest of the episodes were pretty amusing too.

I personally found this to be a very dull finale. Despite seeing Slash a third time, it's only in this episode the guys are intially hostile towards Slash based on the fact that he tried to kill them when he first mutated. They seemed to have forgotten that second run-in with him and the Newtralizer.

Pidgeon Pete. If there is a character I detest the most in the series, it's this guy. We don't need more dumb characters. We especially don't need dumb, unfunny characters.

And the trip to Dimension X felt too much like the first time they went to Dimension X. I understand there's time constraints and things are going to be re-used but it was just so deja-vu and bland.

Leo is hostile towards Slash because he tried to kill him and still doesn't trust him after he saved them but the rest remembered and forgave him immediately. And I find Pigeon Pete pretty cool to watch. His incompetence doesn't bother me because it's not over played . And the Dimension X scene had alot of epic and original fights I don't see how it was bland.

You know some of this episode reminded me of "X-MEN Evolution" in a way:) When the turtles and the mutaminals had to work together and Leonardo was hating and didn't like it,it was like when the x-men and the brotherhood had to work together and cyclops was hating and didn't like it either:lol:
