Consider a covert substitution plot, aimed at unspecified political goals, for which one or more clones are run off and carefully altered to match the damaged original.

For the purposes of anyone who comes by enough information to ask the question, I am another and it's not to be discussed any further than that. I consider that clone," he makes a vaguely planetward gesture, "my brother, and I want to save him from both the man who currently has control of him and the Barrayaran assassination teams who are after them both."
