Not to make everything into a logince ship moment, HOWEVER
THIS MOMENT IS SO CUTE. Why? Because it shows how much Roman knows about Logan. He knows him so well it makes me sick, as was previously shown through the xmas episode when he gave him a 400 word play as a gift, which was so thoughtful and sweet. He knows exactly what Logan is passionate about and pays attention to his interests enough to mention something he likes to get a rise out of him. Despite Logan insisting he doesn't have emotions, Roman knows how to show he doss have emotions, and Logan just accepts this as a fact. It also shows how comfortable they are with each other and how much they rely on their playful banter. Logan canonically hates being corrected, especially when it has to do with his emotions, but when it's Roman it's alright. He's comfortable with Roman and can banter wirh him back and forth, he lets Roman see his feelings. And also the small little smile Roman gives him is so cute, he loves his nerdy bf sm
