I figure that was just the exit for Andrea Thompson's character and not something that was initiated so early on like now. It's clear that they still intended to expand with Talia's character so it's quite possible that the Evil!Talia personality or even idea didn't even exist (at the writing level---Idk about plot level). To try to theorize around the Powers That Be thing, I suppose alicamel's got something going about visiting back at HQ to maybe give some closure to herself, bury her past of what she had with Jason Ironheart. I can't see her trying to give herself up for an experiment though, after what Ironheart told her. But that isn't to say that the Psi Cops didn't knock her out, implant the thing and wiping her memory.
