I say whatever works best for the story. I can imagine the architecture leaving a connection to a handler or creating an automatic connection to who ever you first looked at and touched when you woke from imprinting. I think they would want some type of safety protocol for all former dolls since they were a secret organization.

Didn't notice a handler for Ballard. It's possible one isn't needed if you're not switching imprints, though again, I wonder if he felt differently about the first person he touched.
