Pulse was out and about in the Network; having completed his assigned tasks for the day and checking in on Riche, he went for a jog to clear his head. He was thinking about visiting the library's digital stacks for some light reading when he happened to notice the presence of R.O.B. nearby.

With Dr. Eggman taking over the city with robots, who knew whether or not he was planning on monitoring the networks with attack programs?
