[Dr. Sivana]

I tuned out early, but I cannot stand Will Robinson types in shows that want to be taken seriously. The Starship has hundreds of top level trained engineers, and the doctor's 13 year old kid knows more than all of them. The best opportuniy to off him was when he didn't keep off the grass on that pleasure planet. "Sorry, Wes, but Prime Directive and all that rot. Can't risk interstellar peace or our relativistic principles."

With Troi, it would be one of the many, many scenes with dialogue like the following:

Ferengi: Y-Y-Y-yes ... Captain Picard (heh-hehh), I think I have a proposition that can benefit both of ussssss ...(heheheh)

Troi: I sense deception, captain.

Wow, Sherlock Holmes and Sigmund Freud all rolled into one!

hehe

There are several other episodes that establish Troi can’t ‘read’ Ferengi at all.

I always wondered if she could sense the guys checking her out in that tight outfit.
