I saw a post a while ago describing rba Whirl as mtmte Whirl’s daughter, and initially I thought “oh that’s a sweet way to think of it”

Then with a line from Medix implying the existence of relatives among cybertronians (he’s literally Ratchet’s nephew. Then who’s Ratchet’s sibling????), I started thinking mtmte Whirl could straight up be rba Whirl’s dad.

And what basically confirms it for me is this picture on her locker:

He’s her dad. She is Whirl jr.
