Alison

Alison is an unseen character mentioned in Red vs. Blue Revelation, but was first referenced in Reconstruction. Little is known about her except for that she was a loved one of Dr. Leonard Church who died because of her own failure. The memory of her death lingered on Dr. Church's mind so much that when Alpha was created, a "shadow" of Alison was made as a by-product of the process. She was put into a robotic body and given the codename Freelancer Agent Texas, believing herself to be a real human and interacted with Alpha (who also believed himself to be a human soldier and thought Leonard Church's name his own), remembering him as her boyfriend due to Alison's relationship with Dr. Church. The failure that caused Alison's death is never disclosed in the series.

It is assumed that many aspects of Alison and Tex are similar, at least from the Director's point of view. It is also possible that Tex's relationship with Alpha mirrors that of Alison's and Dr. Church's.
