Ada: You... knew each other?
Leon: Well, the script says I did, but hell if I've ever seen that guy before the cutscene.
Itchy: Look Scratchy, it's our old friend Poochie!
Scratchy: What's that name again? I forgot.

I don't know who Anisa is either, but it's heavily implied she became Jasmine's mother figure after she lost her actual one. If Anisa is that important, why have we not heard of her for 15 years? You can't just invent a character like this when so much already exists without her. Where was she at Jasmine's wedding?
Mels: I'm [Amy and Rory's] best mate.
Doctor: Then why don't I know you? I danced with everyone at their wedding. The women were all brilliant. The men...were a bit shy.

Applejack: So what's with this brother of yours and why haven't we ever heard of him?
Twilight Sparkle: What are you talking about? Of course you've seen him before! He was there when we all celebrated Pinkie's birthday don't you remember? And he was there when we all went to Cloudsdale together. And he showed up that one time Pinkie went insane for a day. (Picture of Shining Armour taped onto those scenes.) Its not like my brother just appeared out of thin air and now were pretending that he was there the whole time.
Pinkie Pie: That never happened! Phhh, lazy writers...
