214722*953 never was good with other synths, her strange skin static and clumsiness makes most synths wrongly assume she has some kind of computer virus, so they tend to go out of their way to avoid her, she prefers the company of biologicals now anyway. Truth is (according to the synthetic clinic) her sensor array is malfunctioning and giving out conflicting signals, despite multiple software upgrades, the problem seems to be impossible to locate.
A lack of damage report seems to make her lose outer plating often... She tends to bump into things and not notice sometimes, hence she's gotten really good at patch ups and runs a repair shop for old technology, frequent customers are usually wasteland scavengers and treasure hunters who bring various nick-knacks into the city.
Some of whom bring her replacement parts... She should stop accepting them (They're probably stolen from the dumpsters outside the synth boutiques) but at the rate she loses tail tips and knee plates she's all too happy to accept gifts from biological admirers!
