This was a fun episode from Next Generation's best Season. We see the crew with their memories blocked early in the show and a new crew member on board. With a lot of suspense they establish their identities with a disappointed Worf being told he's the ship's Security Officer!Eventually it is established the Enterprise is at war with the Lyssians and they are under orders to destroy their home base. Commander Riker and Ensign Ro become increasingly close and even end up sharing a bed! The puzzlement between the crew was fun to watch and eventually Commander McDuff is found out to be the enemy and his plan is thwarted. Watch Worf, even through his memory loss, obey the Captain! The closing scene between Troi, Ro and Riker is quite funny and ended an episode I'm sure was designed just to get Riker and Ro into bed!!
