"The bus isn't real good about sharing it's intentions, I've noticed. If it doesn't like what we're doing, it can yank us back whenever it likes." John huffed. His feelings toward the bus weren't too kindly with the Conductor running around wearing his mother's face. No better than the machines they were fighting.
"The leader of the resistance might do that," he agreed carefully, not liking the turn this conversation had taken. "He put some of them to work helping the resistance. Those were known, though no one understood how he did it. But, mostly, he sent them in where it was too dangerous to send a human, when it was too dangerous to send a human. If you recall our first meeting, Marcus spoke of guardians. He sent one to help...speed up the learning process."
And the hit parade continued. But, he took his time considering the situation before answering Steve's question. "I've only scraped the surface of the bus' systems so far and, speaking from experience, even machines can make mistakes. But, given the level of sophistication I've seen, I'd give it a high chance the bus would succeed. The better question is to what extent the reprogramming was done. There are layers of directives and, as I said, some are hard coded into the system. The most obvious is easiest to test. Let her see the prime target. If she tries to terminate him, the programming's failed. Beyond that it's pretty much a leap of faith unless and until she makes a mistake. You'll have to be very, very clear about instructions and mission directives given, though. They tend to take things literally and their default is still to kill what threatens any mission they see as being given to them."
