Cassian is injured during a mission, he's completely out of it. K2 was mildly damaged. While Cassian is being cared for, and nursed back to health (can take as long as Writer wants-but he is competely out of it, and even if he does ask about K2, he's likely to be ignored because of feverish ramblings etc).
K2 is sent to be repaired, but the OC he is sent to hates everything to do with the empire. And because they are unable to do damage to the empire directly, they decide to take their anger out on K2, who is so very obviously Imperial. They don't care that K2 is senient, or appears to be, in fact this fact gives them more pleasure.
So they write up that K2 is more damaged than he actually is, and really, until Cassian gets better and demands K2 be returned to him, the OC can do what they like and no one is going to come asking.
So this OC essentially tortures K2, I'll leave to Writer how that's done, but I want K2 to be genuinely affected by it. And when Cassian does demand his droid back, the OC, does a half assed memory wipe that doesn't undo some of what they'd messed up in there (like disabling his speech processors when in the company of more than one organic -they wanted the hear the driods confusion and 'pain' etc, but didn't want it to be discovered by anyone else.)
So K2's new behaviour confuses Cassian but he's still recovering, and figures his all too sentient droid is feeling guilty for it or something, but then he starts to notice other things, and when he figures it out he is pissed. Because no one messes with his driod!

Can be any relationship between Cassian and K2.
