I think she's going to travel back in time and stop Rainbow Dash from doing her first Sonic Rainboom, which would make the Mane 6 blank flanks forever. Of course this would also have the side effect of putting Nightmare Moon, Discord, Chrysalis, Sombra, and Tirek in power

I don't know how she's going to travel back in time to make a difference, seeing Twilight's time travel was a complete paradox, but maybe she knows a way, as I can't think of any other reason why they'd go back to how the Mane 6 got their cutie marks for the second time in the series
