AU where Wash is a sort of living doll that is massproduced to be a weird combination of companion, household helper, murderbot, etc, whatever you need him to be really. There’s several different dolls but Wash is a particularly popular model.
His personality is coded but by tweaking some settings you can get a personalized version, the core personality is the same but different parts act differently together based on the settings.
Blood Gulch gets sent one in a drop. They were supposed to get two- one for each team- but the Freelancers found out that some of the sim bases were getting Washbots and they stole one because they wanted one, so Blood Gulch only got one Washbot.
(The Freelancers played their Washbot off as Agent Washington and pretended he was a Freelancer, and the Director pretended he was stupid enough to believe them because 1, he thought it was funny, and b, Aiden begged him to let him watch that train wreck.)
In the canyon, everyone wants to have use of their Wash, and none of them every learned to share so they’re constantly stealing him from each other, even within the teams. Lopez is appalled and tries to get him to join his robot army and overthrow their oppressors, but the end result is that he just ends up joining in the constant kidnappings as everyone tries to get exclusive use of their Wash.
