Liaisons

The Federation is about to open diplomatic relations with the Ilarians and three emissaries come over to the Enterprise and each take an Enterprise crew member to work on an aspect of human emotions that they don't have.

Deanna Troi gets an eager to please Ilarian who falls in love with the human concept of desserts with meals. Marina Sirtis just keeps feeding him sweets of all kinds.

Worf gets an obnoxious twit of an emissary and let's baiting a bear is less hazardous to your health than baiting a Klingon.

And Captain Picard gets to fly with a third on a shuttlecraft that is forced down and he is held by a strange woman who's warm for his form. That one is truly revealing.

Interesting storym especially the Worf part.
