Congrats, Megatron, now Starscream is actively thinking about manipulating his boyfriend. For the greater good. Obviously.

"Hm. Maybe." He frowns slightly in thought. "She does care about his welfare, but at the same time...she might well just encourage him. She might just as easily encourage him. In the grander scheme of things, I think she might believe he can do no wrong. She was one of his very first followers, after all."

So Megatron needs him to keep him from going astray, obviously.
