Stellar Flare: Can't my son be anymore oblivious!?
Twilight Velvet: I wouldn't blame him for not understanding my daughter’s hints when they are this bad…

Then Starlight 'rescues' Sunburst much to Twilight Velvet's annoyance.

Stellar Flare: Why are you complaining about? You already have a granddaughter!
Twilight Velvet: Why can't I have more? It's not like my son is going to have another foal anytime soon, so Twilight is my best bet.
Sunburst: I know you are in that bush, Mum!
Stellar Flare: Well, if you gave me come grandfoals then I wouldn't need to be in here!

Just a stupid idea that came to my mind that I couldn't shake.
