You are the only one on the Nemesis that Megatron trusted, however Starscream didn't like you. Starscream was getting yelled at by Megatron for missing up the mission he was sent on and you overheard so you spoke up.

You: "Hey Megatron, if you really want to yell at someone. Yell at the Autobots, they almost killed Scream. So quit yelling at him for something he didn't do!"

Starscream was shocked that you actually stood up for him, maybe you weren't that bad afterall...
