Idea but

I imagined an Aligned adjacent au where at one point or another where all three are on a rebuilding Cybertron with their own apartments and haven't reunited until now

Starscream and Soundwave have their rid15 designs because those are beautiful as fuck in my opinion

Megs in my opinion has either a frame that's a mockup of his pre-war Megatronus frame or something similar to what we see in "Coming Home" because I fucking loved that fic

On a side note I've been running this plotline where Megs shows up somewhere and Optimus meets him while he's in jail of sorts, and Megs makes a remark about "This feels familiar, does it not?" A bittersweet moment with a helping of this exasperated fondness to it in my mind. I say this because I know in rid Starscream and Soundwave were individually hauled in for a trial, and I adore the idea of there being a rehabilitation program because yes.

I'll be honest I don't really know who Starscream should be with as in this situation I'm imagining wavewave and megop, yes. I know I did imagine Starscream having minibots / smaller sparklings, because I've been thinking about that (the frame ratios are more in favor of carrying for his rid15 frame, which is how this scenario was born.)
