Now, Lord Mark's defective hard drive is going to be removed and junked, and his RAM is going to be given to his older brother.
... Yes. Lord Mark's brain will be junked, and his body used for spare parts for his clone-twin.
It strikes me with some satisfaction that the primary damage Miles took from the cryofreezing is NOT something that he could use cloned parts to fix. Even if he had a bright-new body, he'd still have the same damaged brain causing the seizures.
