I've only seen the movie once so far, and that was about a week ago (therefore my memory might be failing lol), but I think Ariadne seems the type of girl that would've slapped Arthur for what he did before she shows her affection towards him...they just happened to be on the job at the time... haha
Yeah, I know there's been a lot of jokes about kicking Arthur's chair, but hey, it's fun! XD
To be honest, I started thinking about shipping these two since they first appeared in a scene together, so imagine my surprise when that certain other scene came on, lol XDD
Anywho~ Yay, comic practice!!
