In this episode we see J.Ds brother, Dan, return and immediately rush off to sleep with Elliot. When we see Eliot she is in bed with her boyfriend Keith. Dan, at the door, asses the situation and assumes this is about to be a 3-way to which Keith begrudgingly accepts and begins stretching as the door closes.

Does Elliot hook up with them both at that moment?

To answer the question if the Janitor interacts with anyone else but JD? In season 1 Episode 15 "My Bed, Banter, and Beyond" @ 24:15 JD is talking with Elliot about there new relationship and says that it will help other people to know about their relationship, then JD say's like those two gesturing at the Janitor and Nurse Roberts, and the Janitor is vacuuming and blocking Nurse Roberts from walking by and then it goes back to JD and Elliot, and Elliot laughs.

I'm not sure if this is the way to request this, but could we get some numbers on the J.D.'s Girl Name page to show how many times a name was said and number of girls names said per season? Obviously we can go down the line and add but it would be nice to have a quick glance to find out.
