Because they'd be good for each other, like you already said.
and snake already has a precedent for bespectacled nerdy wimps...
PLS PRESENT IDEAS FOR GWYNDOLIN GETTING A DATE
consider: gwyndolin x elliot bc twink4twink
if gwyndolin bent down a little for him would elliot gomez kiss up his arm
he'd probably have to be given the idea first, i can't imagine him coming up with it on his own, but maybe!
he would probably hold hands a lot though
that's a thing he does...
like. in canon after being separated from rean (and worried sick about him) for a month, the first thing he does is run over to him and grab and hold his hand
he also holds rean's hand again if you get his ending.
all the other guys (mukky included) do brofists/handshakes, but not elliot.
machias' is next up at least for me and his is also fantastic so
omfg "there he is, he's the one" elliot thats gay
he makes it sound like love at first sight omg...
