Latent Image (episode)

=== Act One ===
The Doctor visits {{Captain}} [[Kathryn Janeway|Janeway]] in her [[ready room]] to perform her physical examination, since, as usual, she didn't show up. The Doctor asks Janeway to come to [[sickbay]] at her earliest convenience so that he can take a deep body scan of her, and tells her about the surgical procedure he doesn't remember performing on Kim. He has deduced from the [[isotope]] decay around the scars that it must have been eighteen months ago, but Janeway says that she doesn't remember it either. The Doctor asks for a complete [[diagnostic]] of his program and Janeway tells him that [[B'Elanna Torres|Torres]] and Kim are both busy, but he is next on the list.

The Doctor comes to the [[astrometrics]] lab to ask [[Seven of Nine]] for a favor, but she is busy recalibrating the [[deflector dish]] and tells him to come back tomorrow. The Doctor complains that Janeway is "acting like she's allergic" to him, and now Seven, his "prized pupil", won't talk to him either. Seven tells him to state his request, and The Doctor tells her about the surgery (which supposedly occurred before she joined the crew) and asks her to help him run a self-diagnostic. Seven agrees to help him in one hour.

An hour later, Seven comes to sickbay and finds The Doctor inactive. She activates him and tells him that she has run a preliminary diagnostic and his suspicions were correct, but he doesn't remember speaking to her and doesn't know what she's talking about. He tries to view Kim's holo-scans, but the [[computer]] says that the file has been deleted. The Doctor decides to look at his photo album from eighteen months ago and asks Seven to meet him in [[holodeck]] two.

On the holodeck, The Doctor finds that all of his images from the date of the surgery have been deleted. Seven reconstructs five of the images from residual [[photon]]s in the [[holobuffer]]. The images are from a [[birthday]] celebration for an ensign The Doctor doesn't recognize, and a shuttle mission with her and Kim.
