Live Fast and Prosper - S6-E21
Other mistake: As Captain Janeway enters engineering after her sonic shower incident you hear crew members calling out problems on the ship. One mentions something about Deck C and another mentions a problem on Deck 22. Letters are not used to designate decks and there are only 15 decks on Voyager. (00:06:30)
Deliberate mistake: When the Doctor begins to "fade" in the transporter room his mobile emitter fades with him. Since it's made of solid matter and is not a hologram, this shouldn't be possible.
The Doctor: Watch your tongue... Or I'll remove it.
Trivia: Robert Picardo plays the Voyager's Holographic Doctor. Picardo played the same role in Star Trek: First Contact.
Answer: The bio-chambers could be opened from the inside and exited if needed. The induced stasis was not intended as a deep sleep or long-term, but only temporary to protect the crew while traveling through hostile space conditions. External circumstances could awaken crew members. Tom was claustrophobic and highly nervous about undergoing stasis. His anxiety may have prevented a deeper sleep. Tom was essentially sleepwalking and had no memory of leaving the bio-chamber.
