Twilight's speech went as planned. Having studied it word for word, she didn't even need the cards she had made to recite it. With Spike providing the visuals, she put on the best presentation of Cutie Mark Magic that anyone had ever seen.

S05E26 The Cutie Re-Mark Part 2

"See? You can't stop me no matter what you do," Starlight said with a smug grin on her face as she stared down Twilight after stopping the Rainboom once again. "You might as well give up."

"One more round. Winner takes all, Starlight," Twilight said as the dome appeared to whisk her off to another altered timeline.

"Fine by me. I'll be waiting..."

Twilight eventually returned and locked gazes with Starlight once again.

"Since this time is winner take all, I won't be holding back anymore." Starlight's horn glowed in anticipation.

"Neither will I," said Twilight as a pillar of magic turned her into Rainbow Power Twilight Sparkle. "Bring it on, Starlight!"

The fight went on just as before, only this time, Starlight's attacks were all futile with Twilight's new arsenal of spells. The alicorn was creating seeker shots that countered her opponent's beams and started to chase her through the skies, massive forcefields that would capture Starlight and prevent her from attacking, and even columns of light that stopped the flow of time so as not to grab anyone's attention.

The final attack came from Twilight, who unleashed a massive deluge of magic that completely overwhelmed and vaporized Starlight Glimmer once and for all.

The Rainboom was successful this time, and as Twilight and Spike were pulled back to the present, Twilight looked back at the falling ash that was Starlight.

"Looks like your time—" Twilight put on a pair of black-tinted sunglasses "—is up."

"Yeah!" said Spike as they finally left the past.
