You know, Pike's fate on Talos IV seems far less optimistic than the episode suggests. The quality of his life on that planet seems dependent on the extent of the Talosians' mental abilities. If all they can do is simply project illusions, then at the end of the day won't he simply be spending the rest of his days imagining that he and Vina are spending he rest of their lives together when in fact all is he really doing is sitting in a chair in the corner of a room somewhere? (One hopes that Vina remembers to dust him off every now and then). Couldn't he have achieved essentially the same fate by sitting him in the equivalent of a holodeck or jacking him in matrix style into some computer system? He and Vina could only ever have the equivalent of a shared dream since at the end of the day he can't move from that chair.
