What happened? Why did the warlord change his priorities and why the hell did he take the Autobots' side?! Megatron was treated with great distrust on their side. Of course, he started this war, because of him hundreds, thousands of bots died and Cybertron fell. However... Megatron didn't want this war.
The situation is not as slippery as before. Megatron has started to be trusted, he has proven that he can stand behind his words. Entering the room after talking with the other bots, you see a lonely Megatron, whose gaze is fixed deep into the endless space. He sighs heavily and continues to peer into the distant stars.
"Come in, do not be afraid." Perhaps before these words would have caused horror, but now Megatron did not look so frightening. More, you know, melancholic. "...I know I made an oath that I wouldn't remove this cannon until the war was over. I just don't want pointless deaths for a goal that doesn't even make sense now."
