“Oh, Sweetie Belle, one last thing before you go.” Celestia called out to Sweetie, who had her hoof out the door, ready to leave. Twilight glanced between the two as a piece of paper was levitated toward Sweetie. Looking over it, Sweetie realised it was a complicated spell, one that would increase the size of her bags.
“That’s the spell we used on your bags. You will have to get Twilight to cast it each loop start, due to the fact the loops drains magic from the room. That’s what your experiments concluded right?” Celestia glanced toward Twilight, who bit her lip.
“Well, when I gave Sweetie some magic-in-a-jar that was essentially my memories for a loop, it was completely drained the next loop. As least, that’s what my notes say.” Twilight tried to keep the doubt out of her voice. Could she trust her past self to run proper tests?
“What would happen if the spell was drained of all magic?” Sweetie made herself a mental note to remember to remove the contents of her saddlebag when she went to bed on Fridays, or when she stayed up for a loop’s end.
“Probably split apart, both ruining your bag and sending all the items everywhere.” Celestia nodded once, satisfied with that hypothesis.
“Alright, thanks for the warning, see ya!” Sweetie smiled warmly as she waved goodbye to the three, and ran off to find her friends. If she was lucky, she might be able to get some fun out of this loop with her newfound magic abilities.
Which is to say, her new ability to explode on a whim, but Sweetie ignored that fact.
