Since finding Jayne in the Sensoriums, Chell decided she was going to return to that field as soon as possible. It seemed easy enough--just think about what you wanted to see, and there it was! Amazing. Sure, there was the problem of not remembering many places outside of Aperture, but the sun and sky and expanse of grass was easy enough to

So she returned to the room, Wheatley in tow, and was surprised to find that the room was not only in use, but it was strikingly similar to how she'd found it when Jayne was there.

It did not take her long, however, to find the crucial difference. That was definitely a cake, over there, and the sight of it instantly set her on edge.

The cake was never, ever, ever legitimate. And with GLaDOS on board, this cake was almost certainly a lie. It was always a lie.

But it looked so good.

Chell often let her curiosity get the better of her. She knew it was a bad decision. The worst decision--this was obviously a trap. But maybe she could just...touch it. See if it was real.

Very, very slowly, she took a step into the field, and then another.
