Q; Why wasn't Riker surgically altered to look like a Tilonian when he woke up on the table?
A; We might assume that the Tilonians had altered him back.
I notice that, compared to some other episodes, Beverly is having a small hair day. This may seem like a sexist comment, and indeed it probably is. I find it difficult to regard La Gates as anything other than a sex object most of the time. Just compare Frake's acting in this show to McFadden's in 'Remember Me'.
When Riker is in the turbolift looking at the naughty Tilonian walking around the corner, why does the lift door take so long to close?
Bearing in mind that the Enterprise has more than a thousand souls aboard, why do only around twenty watch the play?
The mind scanner which the Tilonian doctor uses to project Riker's feelings as represented by his crew-mates is, I imagine, in fact a clever plot device to keep the other main characters somehow involved.
