: Pinkie Pie takes on a "fortune teller" persona, using a crystal ball that she claims shows the future (though she later admits she’s just a pastry chef).

: The episode draws heavy inspiration from Metal Gear Solid (Twilight's stealth gear) and sci-fi classics like The Terminator and Quantum Leap .

: As the deadline approaches, Twilight becomes increasingly ragged—sporting an eye patch and a messy mane—as she tries to break into the Canterlot archives to find a time-travel spell.

Twilight Sparkle is visited by a disheveled version of her , who attempts to deliver a warning about a disaster occurring "next Tuesday" before disappearing. Panic-stricken, Twilight spends the next several days obsessively trying to "disaster-proof" Ponyville to prevent whatever catastrophe might occur.

The episode is the 20th episode of the second season of My Little Pony: Friendship Is Magic . It originally aired on March 10, 2012, and is a fan-favorite for its take on time-travel paradoxes and Twilight Sparkle's descent into frantic "over-thinking". Plot Summary

: When Tuesday finally arrives, Twilight realizes there was no external disaster. The "catastrophe" was her own stress and lack of sleep. She uses a time-travel spell to go back and warn her past self not to worry, only to realize she is the one who caused her past self's panic in the first place—a classic predestination paradox .
