I'll be honest. I thought this would be an easy speech to write, but you know what, it isn't. All of these girls perfectly emulate one part of GLaDOS, One of them likes to play with neurotoxin, one would kill companion cube at your birthday party for a laugh, one generally just wants to conduct tests, one is her human personality and the last one, well the last one just really really wants play a game with you.
With all the varied actions and the way they fit together, these lovely ladies are almost like some kind of personality cores connected to a central hub. D:
Let us all pray diligently we never get on the bad side of these girls lest we have to spend ten years in the chamber where all the robots scream at you.
