Alone.

Twilight was now alone with this new alien thing, and the Doctor was nowhere to be seen. He had disappeared a few hours ago, but Twilight hadn't bothered to be worried, or even think about it too much, because the Doctor always found a way to return alive fairly quickly. But now that this strange flame in the shape of a pony was closing in on her and she had no Doctor for help, she was quickly running out of options.

twilight and flamepony both stop and look as the doctor comes trotting in through the door.
"sorry about that, had to use the restroom."
his claim confirmed by the toiletpaper that had stuck to his hind hoof.

Apparently not noticing the Flame Pony, he stuck his head in the refrigerator.
"Whoops, it looks like we're out of lettuce. Twilight, if you'll excuse me, I'll go buy some. This world makes lettuce very well!" And with that, he walked back out.
Now it was just her, the Flame Pony-no, make that two, another one arrived-an empty refrigerator, and the odds triple-stacked against her.
Damn.
