sorry milly but
unicorns are about 10000x cooler than pegasi
just sayin'

BUT MORE SERIOUSLY they can probably totally team up as superheroes at some point, even though milly's strategy of punching things into oblivion might not completely work with his style.
tbh they could also probably meet at the café she and teddy work at because you know he's hipster enough to order a (insert bullshit drink size name) vanilla-orchids-whatever latte with extra cream with a straight face.
also i'm laughing because depending on how things go i could 100% see eusine develop a crush on her (though he'll probably be like ~hello ladies~ from the beginning since that's just how he rolls.)
this can only end in disaster. ridiculous disaster.
