I like Mari's English dub voice overall, but I'm iffy on her using Spanish (I think?) instead of French. But I'll admit that's for entirely personal reasons - I know more French than Spanish, so I'm much more likely to actually understand Mari speaking random French phrases than I am her speaking random Spanish phrases. Here in this episode, there's a few words Mari speaks that I didn't get at all, and I guess that's probably due to Mari speaking Spanish words I just don't know. That being said, I do love how Mari pronounces "Si!", which is one of the precious few Spanish words I do know. Mari's delivery of it just sounds nicely comical to me.
