“It’s a brilliant spell Spike.”

“It’s a weird spell, what possible reason could there be to instantaneously swap you with Princess Celestia via magical teleport?”

Twilight rolled her eyes and shook her head with frustration. It wasn’t the first time that her annoying lab assistant had to ruin her excitement at a brilliant new piece of spell-crafting with his down-to-earth, rain-on-your-parade ‘logic’. Why couldn’t he see that a reverse-inverted teleport matrix, woven through a thaumic teleport field array created a beautiful symmetry that allowed for extreme distance teleports, so long as both of the targets were alicorns?

“There’s plenty of reasons! Like…” Twilight chewed her lip.

“Like…?” Spike crossed his arms, looking expectantly at her.

He was so annoying! Why didn’t he see the elegance? Anchoring a teleport to two alicorns gave it a huge amount of potential energy, enough to require only the lightest touch of magic to kick off the complex spell, which would then swap the two alicorns across vast distances at almost negligible cost!

There had to be some use for the spell! “Like… if I need to get to Canterlot quickly so that I can speak with…”

“Princess Celestia… who would be in Ponyville.” Spike arched an eyebrow at her, shaking his head sadly.

“OR… or…” Twilight hummed, her mind racing for reasons. “What if Celestia was in danger, about to be kidnapped by some evil menace?” Twilight slammed one hoof into another excitedly, her confidence rising at this new use-case, “I could -”

“Swap with Celestia, putting you in just as much danger as she was in?” Spike spread his hands in confusion, still shaking his head.

“Maybe I could handle the danger better!”

“Than Celestia?”

“I said, maybe.” Twilight groaned. There had to be some use for this spell… it was just too good to be relegated to her big book of arcane arcana! Too many of her brilliant spell-matrices ended up there, useless works of magical art... like ships in bottles: fun to look at, but not much else.

“Heh, maybe you could swap yourself with Celestia so I could ask her if she can think of good use for your new spell.” The diminutive dragon chuckled, grinning impiously at her.

‘That was it!’

“Spike, you’re a genius!” Twilight brightened, charging up her horn.

“What? No, I was j-”

“We can use this spell to have Celestia give you information and directions directly!” The glow on Twilight’s horn grew brighter and brighter, filling the map-room with blinding light. She giggled, eyes widening with too much intensity - she loved her spells, and if Celestia could find some way to rescue this one from the refuse bin, she’d be over the moon!

“Twilight no, she has dragonfire messag-”

“I’ll let her come up with some good ideas for the spell, make sure you write them down when she’s here Spike!” Twilight laughed, cutting off her assistant. It was one of those laughs… a laugh that betrayed that the mare was a little too excited about the intellectual pursuit in question.

It didn’t even click that perhaps she should have asked the princess first.

“Twilight! No!”

*CRACK*

*POOF*
