I have two equal and conflicting headcanons for Ken when it comes to the rollerblades. Bc he brings them everywhere he goes, so you'd think it's something he does extremely often and is so so so good at (but never as good as Barbie obviously)
But having been reminded of that interview where RG didn't practice at all before the scene and was just terrible at it... It really would fit that Ken brings them everywhere he goes and can't even fucking skate
