This introduced Deanna's Mom and one of TNG's most enduring guest characters. A prearranged marriage is at hand for poor Deanna who is betrothed to a wimpy young med school student type fella called Wyatt. He is somewhat surprised as Deanna is not at all as he would have hoped. The Enterprise is in orbit of an idyllic planet called Haven. A Tarellian ship arrives on the scene, Tarellians having died out as a race a long time ago. The woman Wyatt has been dreaming of for years is on board and she's been dreaming of him too. He eventually beams himself over and the ship departs. In a pretty lame episode which didn't help a show as young as this. Watch out for Wyatt's father played by Robert Ellenstien who had previously played the Federation President in Star Trek IV, The Voyage Home.
