After Rob leaves, Brad starts sniffing. He is suddenly aware of so many new smells. He sniffs his pits, his crotch, the nurse's lunch.
In the other room, Brad overhears the nurse talking on the phone. She is saying, "Yes, I suppose isolating him at the zoo might be the best course to take. No he does not seem violent, but I suppose a tranq gun would be sensible. Slowly Brad backs toward the open window. A produce truck is outside unloading boxloads of bananas. The smell is overpowering to Brad, he quickly drops down from the nurse's window on to the roof of the produce truck swinging like Tarzan from a telephone line instead of a vine.
Inside the nurse's office, the line suddenly goes dead. She clicks on the receiver, but no dial tone. Oh, well animal control should be here soon. She goes out to reassure Brad and keep him calm, but he's gone!
