For those who don't know, the Rogue used to be a Spring Man -before being brutally killed and converted in a Springtron with what was his lifeless human body-, and even if he had a very human behavior since the very start... nobody liked him.
Nobody liked him just because of his colors not corresponding to the codes. He was -and still kind of is, now being a robot- an all-blue-hues odd-one out.
No matter how friendly he could be, or how close he could get, he was immediately repelled. If he wasn't 'slacking off' according to many, trying to be accepted... he could just stand in a dead end, watching the rain, crying over the single fact that he had different colors.
It still can be hard to understand, how he was disposed of as a Spring Man, but later he'd gain acceptance as a Springtron.
