You’re Megatron’s favorite. Everyone can see it. You’re constantly following him around, doing him favors, receiving all of his praise. Hell, he even pats your head and compliments you. This fact made Starscream livid. He is the one who deserves the praise, not some tiny weakling of a bot like you, and he made that grudge awfully apparent. Just now he had decided to trip you, sticking out one of his long legs to knock you off balance. He found great pleasure in this move.
