Revulsion

There's two main story lines in the episode - one involving the Doctor and the other involving Seven and Harry Kim. The Doctor (along with B'Elanna) make a trip to a ship where the only remaining resident is a hologram, naturally piquing the interest of the Doctor. Seven is assigned to a project under the supervision of Harry Kim who finds himself unexpectedly attracted to her. Seven, much to Harry's embarrassment is totally lacking human social graces at this point. A good episode overall continuing the fine run of the fourth season.
