Aurora 'Rory' Morningstar finally had her life on track.
It only took self-actualising the ability to time-travel, nearly getting killed by a lunatic with a grudge against her dad and finally getting back home after getting the catharsis she'd longed for all her life.

She's very not amused - snd she intends to make that everybody's problem.
