- Hilarious in Hindsight: Try not to laugh at how Chakotay looks when he ages; his face is elderly, but from the neck down he's still oddly buff for such an old man. Fast-forward ten years, and watch Robert Beltran in interviews or con panels. His hair is silver, his face is wrinkled, and he still looks like he could kill you with one punch. Guess his appearance wasn't so far-fetched after all!
- Les Yay: Janeway gives mouth-to-mouth to a pretty female Red Shirt, then goes off the deep end when told She's Dead, Jim. As reviewer Jim Wright pointed out, that's more same-gender physicality than the episode of Ellen it aired against.
- Nightmare Fuel: Combined with some Paranoia Fuel. Invisible aliens, poking and prodding at your body, messing with your physiology, potentially until you die from it. This might be one of the creepiest premises on all of Voyager. And that's not even taking into account the Squicky visuals involved, such as seeing Tom and B'elanna make out in x-ray vision.
- One notably disturbing moment is Seven, once her cortical node is adjusted, getting into the turbolift and being joined by two aliens who immediately start applying instruments and doing, well, weird shit to her head. She's fully aware of this, and has to remain perfectly stoic to keep up the facade.
