We pick up where we left off with the last episode. Elliot and Keith are still enjoying all the advantages of sex with no emotional strings attached. This is continuing to honk off J.D. since he doesn't like Keith, which has nothing at all to do with the fact that J.D. might still have feelings for Elliot and is jealous.

While that's going on, Kelso is upset because a bird has flown into the lobby of the hospital. When The Janitor acts like it's no big deal, Kelso explains that birds can be major carriers of infection, which, of course, is a bad thing in a hospital. The Janitor keeps the bird and bonds with it, teaching it to do his dirty work for him. The bird goes around stealing pens and causing other assorted mischief.In the meantime, J.D. devises the perfect way to get Keith out of his hair: He'll suspend the next person who screws up something with a patient for two weeks. That plan ends up backfiring on him. The one intern he likes, whom he's nicknamed Cabbage, is the one who's made a number of errors in patient care.

Oh, and that tutorial on how quickly infection can spread through a hospital? It was done for a reason. Mrs. Wilkes, the nice old lady who we've seen for a couple weeks now, and who is being discharged, becomes the object lesson for that danger.

We're left with a "To Be Continued..." That's a rarity for Scrubs, since almost all the episodes are continued in some way, shape, or form to the next one. It's a bit of a heavy-handed way to signal something bad is going to happen to the nice old lady whom everybody likes.
