It is good that they are still on the show, and around. I think writing them out completely would have been a huge mistake. I remember the various cohorts of "interns," on Chicago Hope. I don't think they meant to make the ones with the horse from first season permanent figures. However I remember during season three, they brought an annoying group who did mysteriously vanish midseason. The one with the crush on Aaron, did you mean the punky nurse Maricella? She wasn't an intern, but an intended love interest for Aaron, which was just wrong on so many levels.
