Lessons is an episode of The Next Generation, the nineteenth episode of its sixth season.

Picard falls for Lt. Commander Nella Darren, a Starfleet officer in Stellar Sciences. After he suffers incredible loss and pain when it is believed she has died during a mission — upon her safe return, Picard realizes that he is incapable of carrying out a relationship with someone under his command and also fulfilling his duty to Starfleet. Cmdr. Darren requests a transfer, and is never heard from again.

"Lessons" brings out of storage Picard's beloved Ressikan flute, which he learned to play during the critically acclaimed episode The Inner Light.

The highlight of the episode is widely considered the duet with Picard on the flute, and Darren playing her keyboard.
