Okay!! (So i am gonna bring up my Whispurge headcanon a tiny bit too just because they do go hand in hand for me, sorry lol. Just dont read past the dash if you dont care about it.)
The sonurge dynamic for me is kind of near entirely one sided as far as like actual romantic interest. Like for sonic its a case of wanting to challenge and tease her to keep her mind off things and rile her up in a friendly way. Maybe a little flirty but for him its nothing serious. He enjoys their banter and their rivalry is a fun one.
But for surge i think its a complete case of crossed wires. The internal battle with her programming that puts him in a place of fixation in her mind by default but now is fluctuating rapidly between “i hate him so fucking much” and “i think he’s clearly amazing and i think i like him”. But either way its a struggle with the thought that the only reason he’s on her mind this aggressively might just be because its what she was made to think about.
I don’t think sonic would know about this internal conflict for a hot minute since i think she wouldn’t explain until it peaked the boiling point but the second he figures out how deep this goes he wouldnt keep this going. Hes not an asshole like that so ultimately this is my Toxic Doomed Ship where they have to eventually keep distance anyway by the end.
Even still when its good i think its really good, its just never going to last without Surge having some kind of breakdown.
Comparatively i think my whispurge headcanons also play on this rivalry dynamic between whisper and surge (definitely a more aggressive hands on one than the one with sonic. Fisticuffs followed periodically by adrenaline induced smoochin) but with those two its definitively, unquestionably a choice they’re both making of their own volition to interact like this. Even if it does carry some doubt or confusion on whispers part mostly about whether she really can trust Surge.
I think two commiserating aggro types can find some comfort with that and ultimately help each other be better than what they are by both of them having pretty tragic pasts they can relate to. (I think tangle and whispers dynamic is also extremely important but she could use another angle like that). Something i dont think Sonic is in a position to ever fully do. At least not until surge already gets all her shit sorted.
