"Because Gronius is hardheaded into his moral values." Song said, trying to hide in what seemed to be a few traces of zealously. "When you like what you're doing and what to go on and continue doing it, you don't let yourself beaten down by the ones around, you prove them wrong or ignore them and continue living your life the way you like it, instead of the way others dictate it for you. Or at least this is what my twin says. It's up to you if you believe it or not, but it's clear that he really, really does. This is why he continued staying, in hopes that, eventually there will be a change. But the Maximals are just as stubborn as him, and wouldn't change."
"Look, listen to me." Gronius said, waving his shaking hands in the air. "In the possibility in which we escape, we run away, what comes next? What are we going to do? Are really going to colonise a planet? And if so, where will we find that planet? Where will we find the resources needed to create any long-lasting settlements? Or heck, even the resources that we need to survive! And who is going to lead us anyway? The kid? Under no circumstances or context I will accept that kid leading me, even if he is the responsible one for our freedom!" Gronius said, having a dialogue more with himself than with Thundercracker.
