Bruno ducked into the library, and found an open study room to study Karl's work.
Karl's kept a journal in which he detailed his experiment with the nanobots he stole from his father. They were self replicating, so he created a batch, and returned the same number to his father's safe. Then he programmed the nanobots with basic human and canine DNA, and put them in a container of body paint.
"I'd love to have seen naked Chad painted with nanobots," Bruno said allowed.
The tablet was listening, and the AI opened a video window showing Karl's recording of Chad's transformation.
Bruno replayed it on a loop while he jerked off. When he was done, he read on.
"Hm, so Karl deactivated the nanobots replicating feature. Well, I think we need to turn it back on, so Karl can get a healthy dose of nanobots, and then my fun can start."
Chad grabbed his belly. What had he been eating? Dog food? Karl and Brad?
Then he heard Bruno's voice in his head telling him to be a good boy, and play along with Brad and Karl that Bruno had a plan.
Next Bruno began downloading more types of DNA.
