#i will never understand why he stuck his thumbs in riku’s mouth #i can’t watch it without thinking sora’s like #’YES THIS MAY BE RIKU BUT IS IT REALLY HIM LET’S USE THE DENTAL RECORD METHOD’ #or possibly #’YES RIKU’S HERE BUT IS HE OKAY DOES HE HAVE ALL HIS TEETH OKAY NONE ARE KNOCKED OUT HE’S FINE’
I’m thinking it’s for a variety of reasons, most of them very silly but which probably make sense to a 14-year-old.
For one thing, he’s stretching his mouth to look like Riku’s normal grin to make sure it’s right- and for another, if it were anyone else but Riku, they’d probably react a LOT differently. Riku still goes “wtf are you even doing Sora omg get your hands out of my mouth,” but it’s a totally Riku reaction. And for all we know, that’s something Sora did all the time anyway, because he’s a tiny dork and does silly things?
Also, it’s possible this has cultural connotations I don’t know about. I dunno, that’s what I always thought.
