The 118 had gone on camping trip. They just wanted to relax, chill. They had no idea that while Buck was dozing off in a hammock, a bat had landed on him and stretched him with its teeth, breaking his skin.

When they got back to LA, Buck had no idea that he was now, infected with rabies. After a while he started to get headaches. Next came the lack of coordination, Bobby had noticed this on calls. Then hallucination. Then hydrophobia. Buck had no clue, he was starting to panic.
