It wasn't long that Sarah was gone, but it was time enough to make the difference between returning to the scene she had left, Ben and her brother, and returning to a Hell God sucking out her little brother's brain. For a few precious seconds after opening the door, she could only stare, too late to do anything as Glory's hands dropped away from Toby. Sarah had seen that face on the boards enough to know who it was – and to realize what she had done to Toby. Her baby brother. An innocent in many ways, a child who would never harm anyone if he could help it, happy and smart and eager to embrace the world – and Glory had taken that away from him.
It was when that realization settled in that things exploded inside Sarah. Where Ben was, where Glory had come form and how, it didn't matter. Only Toby's state did. The restraint that she kept on that unfathomable well of her power, a careful hold that allowed her to live an 'altered normal' life for the most part, allowed her to keep hold of every piece of her humanity that she could, snapped away like a broken rubber band and the power flowed out, unchecked and wholly wild. The change that came with that, the alteration of her appearance from Sarah to the look of the Goblin Queen, the counterpart look one Jareth had flaunted but a look Sarah always kept buried – kohl-rimmed eyes to black clothes to the disheveled, but thankfully not 80s like, hair – wasn't gradual. It was all but instantaneous.
"You bitch." It wasn't spoken, it was snarled, more feline than human, as revenge, payment for what had been done, ruled her actions. She didn't have to think, didn't have to struggle or analyze over the ability that had still been beyond her, to move seamlessly between Los Angeles and the Underground without the use of portals. The apartment simply melted around them and became a corner of the Labyrinth. The sky was black above them, the ground rocky and uneven and threaded with glowing red rivers of something that boiled, the walls of the everchanging maze stretched out around them, the air pulsing with something feral and livid and ugly.
It was the heart of Sarah's pain and fury, a place formed from every loss, every pain, every stress Sarah had suffered since becoming the Goblin Queen. Time would be essentially stopped in Los Angeles while it ticked on in this place because Sarah could make a thousand years pass in her domain in the space of a few seconds in another reality. Those at home, save perhaps Peter, wouldn't even notice she had gone before she was back again.
And if it took a thousand years to annihilate this Hell God, so be it.
"Let's see how you like being at the mercy of another, powerless with no way to fight back," she said with a smile that held no mirth and then snapped her fingers. The power she had feared more than most of the others, because she didn't want this kind of power over Peter – or anyone else, really – she now embraced wholly to not only even the playing field but, as Sarah imagined, put it solely in her favor. It would cost her another piece of her humanity, what she was doing, but she didn't care. Glory was going to pay.
And there was no doubt in Sarah that it would work. This was her realm. What she wanted happened. Eventually Glory would start to regain her powers – and Sarah never considered it would be anything but a slow regain – but for now, Glory was at the mercy, or more accurately the utter lack thereof, of the Goblin Queen who had been pushed too damn far.
