I'm trying my hardest to make this good Wolfslayer321

Megsy
No, that information just switched your title from The Princess of the Decepticons to The Queen of the Decepticons. Nothing but that changed.

Breakdown

Yes, he didn't tell anyone from fear that Megatron would take advantage of your status. He only took advantage of it so he could call you Princess and tease you about it.

Starscream

Yep, oh it was one of the best things he had ever heard besides you telling him you loved him and agreeing to be his sparkmate/girlfriend.

Your status brought him closer to becoming the Leader of The Decepticons. Though you both are still confused by whether or not being sparkmates makes him a prince or not.

Predaking

Nope, you're already his queen so that information didn't matter to him. Royalty or not, you were still his queen.
