Heros and Demons: a recreation of Beowulf on Holodeck 2 gets infected with photonic energy, with Harry, Tuvok and Chakotay missing, presumed dead, the HoloDoc is sent in to investigate.

Second use of the holodeck, and already they're having a holodeck malfunction. More trouble than they're worth, those things.

Tuvok says the description "hair straight and raven black, eyes bright with fierce fire, the burning gaze of a hero" corresponds to Harry. Well, the hair's right...

There are no demons in Vulcan literature. Well, of course not. No fun at all, those Vulcans.

HoloDoc doesn't even apologise to the Grendel creature for the kidnapping of the two photonic aliens. Tsk.

Neelix does not appear in this episode. What a shame.
