Guess the reference.
-Do you not remember the last time I invaded Celestia? Why would you draw your power against me again?!
-You're destroying our world Chrysalis! You and your Changelings can NOT be allowed to your campaign!
-This world belongs to the strong Celestia! It belongs to ME! Don't you remember Canterlot?! Don't you remember when I defeated you?!
-I remember everything on that day...AND IT CHANGES NOTHING!
