In the 93rd episode of Star Trek: Voyager Seven of Nine is hallucinating and after the doctor hotwires his mobile emitter he finds her in engineering pointing a rifle at an imagined alien named Trajis Lo-Tarik. The Trajis hallucination vanishes at this point and Seven and the doctor have the following dialog which urks me every time I see this episode:
The Doctor: I believe so. When I studied the gel pack I discovered the radiation was producing a degradation in the synaptic relays. I'm guessing there's been a similar effect on your Borg implants. The radiation could be altering the neurotransmitter levels in your sensory nodes. That would explain why you're hearing voices, seeing images.
Seven of Nine: It seemed real.
The Doctor: Hallucinations usually are. That's what makes them so frightening.
Shouldn't the Doctor have said "hallucinations usually do" instead of "hallucinations usually are?"
I must be wrong because I don't see how the script writers, director, producer, and actors would all overlook such a grammatical train wreck unless there was a reason for it.
Maybe it was because the Doctor's program was degrading?
