I M CONTINUING THIS STORY BECAUSE THE GUY WHO ORIGINALLY WROTE IT WAS A DOUCHE...ENJOY When the facility is raided by a squad of Daleks, GLaDOS is simply thrilled at the chance to torture new and fascinating test subjects.

This is a one shot. I've found no crossovers where Wheatley is The Doctor and Chell is his companion. So I wrote one. You can just assume Wheatley is the [redacted number] incarnation of The Doctor.

The Doctor and Amy go on an adventure through Aperture.

The TARDIS malfunctions (again) and sends the Doctor to Aperture Science, where he quickly makes an enemy of the facility's resident AI and an ally of Chell. (Set during Portal 2). This is my first story on here! Probably going to be about 3-5 chapters.
