Flurry: Really Mum!? Just because you are the Princess of Love doesn't grant you the right to tell two ponies to go and start a family!
Cadance: Flurry, would you even contemplate having one with Starfire?
Flurry: That's OUR choice to have! We aren't even married yet!
Cadance: That can be arranged easily for the two of you if you just ask!
Flurry: That's it! I'm LEAVING!
