Twilight:“I’m sorry? Sorry for what?”  
Pinkie:“Oh you’ll find out, just eat the cake already, come on you know you want to”  
(twilight realizing somethings missing)  
Twilight:“where’s spike?”

Pinkie:“eat the cake, it has a surprise in it, some on do it!”  
(twilight uses her magic to whack pinkie with the pan of the cake, knocking her out. Just seconds after that spike appears)  
Spike:“hey guys, sorry you haven’t seen me^ all day i was with fluttershy an-…(sees pinkie on ground)….what happen?”

Just eat the cake Twilight… the sooner you do the sooner Pinkie will take off that costume. You REALLY don’t want the CMC to get nightmares,.. or even worse IDEAS from THAT.
