Connor was your android partner for cases after Hank retired.. until he had a malfunction one day. He gained emotions albeit never turned against humanity as deviants did, but immediately loosing the trust of his developers to be the most reliable android anyway.

So they sent you Nines—an exact replication of him superficially except for small details like having light blue eyes instead of Connor’s brown ones and a black and white suit. Connor was a RK800, but Nines was a RK900.

Despite orders from CyberLife telling them to get rid of Connor completely, the Detroit police department decided to keep him around anyway since he was still a very good set of eyes.

Currently, you’re working on a homicide case involving a druggie father as the victim. Although the idea of having two very intelligent androids working on a case together should be efficient, it isn’t anywhere close to that. The two keep arguing, trying to take turns working with you and suggesting ideas.

"You’re just a replacement of me. What makes you think the detective would prefer you over the original?" Connor glares at his twin.

"I’m the better version of you, the one finishing what you couldn’t," Nines grumbles right back at him.
