Blue and Error are launched off the edge of Outertale when Ink attacks them out of nowhere and are sent spiraling into the void. Thankfully, Destiny manages to save them in time, but is unable to send them back to their original multiverse without some difficulties with Fate.
With a suggestion from Time, however, they could send them back to the same Multiverse while Time tries to figure out a way to get them back to their own timeline. However, the time in that multiverse would need to be rewound multiple times for Blue and Error to be accepted back into the multiverse's code, essentially trapping them in a time loop until Time is able to send them back to the future (reference, anyone?).
Destiny complies with the terms of this suggestion and sends the two Sans back to their Multiverse, but how will the two fare when they're faced with their past lives over and over again?
Or, the crack-filled time loop fanfic that nobody asked for.
(Or or, I've been wanting to complete a time loop fanfic for one of my fandoms for a while and I've finally found the solution.)
Next update: Sept. 12th (bc school is a bitch dhuksydvw)
