This is a great post about GLaDOS and Chell from the video game Portal! GLaDOS is an artificial superintelligent computer system and Chell, documented as Test Subject #1 but previously as #1498, is the silent protagonist of Portal and the single-player campaign of Portal 2. She is a former Aperture Science Test Subject.

More so from Portal 2 ,but there are “Clues” in Portal, I got the impression (Head Canon) that “chell” IS the daughter of the Admin Assist, that they “Used” to create GlaDos. Whether you assume a consciousness transfer, or a copy/write process that kills the original. “SHE”, The assistant (not knowing what was planned) brought her “child to work, day.” Hoping they might reach her AUTISTIC Non verbal daughter. When she was grabbed and “Used”. Chell, was a problem. A witness and still an emotional connection GlaDos, remembered (at least) having.
Them grabbing her and putting her on “ice” (as a genetic sample for the next Gen “GlaDos” experiment in order to save Cave Johnsons “Life”, by transfering his complete awareness, out of his dying body), triggered her releasing the nerve gas. Cloning the sample to recreate her daughter, so she could have her again, became a journey to release her. All the problems of Portal 2 are the left over effects of 7 programmers trying to take control of GlaDos, in order to save their lives. Westley is based on a download of one of the employees mind. Setting the clone production in action, was the last act of GlaDos, when Westley finally took over.
Which (as usual) reclaimed as his idea and just rolled with.
Sets up ONE HELLA Homecoming for a potential Portal 3.
