[Quintessa growls because Codylight called her a Prime wannabe]
[Twilight hugs Ryan]
Twilight Sparkle: Why are you laughing?
Ryalight Glimmer: I'm sorry. This is the part where I'm suppose to be angry. Full of rage. Insenced beyond belief. Once again, you broke free of my girfriend's control. I should be rather upset see, shouldn't I?
Scrappy-Rex: And in fact, we're furious! But, Ryan looked over one detail, you purple-winged pony freak. Now that Ryan got your teacher safe. All we have to do...
