OP here: it could be that Steve sees similiarities between Eddie's parents and his own, except his didn't outright leave him for good even if they're never around and they are also shitty parents. Steve can be conscious of this or not. So, yes, he wants to help Eddie process this and also embrace all of who he is and show him he's worthy of celebration and love but it's also cathartic for him because he knows what it's like to be neglected and abandoned. *sobs at own prompt* I also just think it would be cute and potentially amusing seeing Steve try to hype up all things French/whatever nationality Filler would like to focus on :')
