When Tuvok is being held in sick bay behind a security force field, the Doctor freely passes through the field, as holograms are able to. However the medical padd he is carrying should not be able to pass through the force field, as it is made of normal matter. A possible explanation is that the padd itself is also holographic, but this would be unlikely.
In sickbay, after being sedated, Tuvok's head moves forward before either Captain Janeway or the Doctor even touch him.
The head of an unconscious person will not remain in the same place as the person is being carried or lifted. Yet, Tuvok's head remains stationary as the Doctor and Captain Janeway pick him up off the sickbay floor (indicating that he's really not unconscious).
When Tuvok begins the mind meld and Suder's face appears in a close-up, the outline of the black contact lens in Suder's left eye is visible with a slight curve of light brown iris behind it.
At about 27' in, when Tuvok is talking to Suder, actor Tim Russ (Tuvok) mispronounces the word "regimen" as "regime", which makes no sense in the context.
Suder is usually referred to as Crewman Lon Suder, except for when Captain Janeway is making an entry in her log, calling him Ensign Lon Suder.
The Doctor's psychological assessment of Suder is that he is not insane or bipolar, although being bipolar does not make one insane. However he fails to point out that Suder shows all the classic signs of being a clinical psychopath, and it would be obvious to a first year psychology student that he is. A true clinical psychopath is incapable of experiencing emotions, including guilt and remorse. Suder never appears happy, angry or sad, he never smiles or laughs and he even states that he never feels anything. Considering the Doctor is also an expert on psychology this is something he should have pointed out in his report.
