Spoiler Alert!
In one of the episodes it is revealed that Ryker is Ortega's lover and police partner!
Bancroft intentionally put Tak into Ryker's body to mess with Ortega because he felt she bungled the original investigation to solve his murder. And he felt she didn't give him enough respect.Later you find out Ryker was framed for murder; So Ryker's sleeve was ripe for the taking.
Bancroft was also mad at Ortega because she ruled his death a suicide. That means Bancroft is a coward and he could not let that insult slide.
Rei was also angry at Ortega for failing to show her the proper amount of respect and that caused Tak to respond, "What's with you Meths and respect?"
