Forum:Chell's origins

Possible Portal 2 spoilers ahead, be advised.

I noticed at the Bring your daughter to work part the overgrown potato-science project had Chell's name on it. This confirms that Chell is in fact a daughter of an employee and not a random test subject. This also means that her parents might actually be in the cryo-storage as Glados implies at one point.

Proof: 

The middle panel's bottom right has "by Chell" written on it.
