TNG Season 4, Episode 20 Qpid

Not one you really have to watch unless you became really invested in Picard’s romance plot from “Captain’s Holiday.” However, it’s worth watching to see the crew’s reaction to the relationship (finding it hilarious) and of course, Q’s (offering to help while acting the entire time like a spurned lover). With the entire crew transported into Q’s make-believe Robin Hood adventure, it’s clear everyone involved in the making of this episode had an absolute hoot.
Even Worf seems a little bit merry.

Plot

Captain Picard is working late on a speech that he will present to visiting archaeologists when Counselor Troi tells him that the council members have arrived and been assigned quarters. Picard returns to his quarters and finds Vash waiting for him, and the two kiss. The next morning, the two are sharing breakfast when Doctor Crusher arrives and offers to give Vash a tour. Vash expresses surprise and slight anger at the fact the Captain hasn't told his friends about her and confronts him about this at a reception for the delegates. After the reception, Q returns to repay Captain Picard for saving him in "Deja Q". Picard requests nothing, so Q decides to save Picard by testing Picard's love for Vash.
While Picard is addressing the delegates, Q transports the bridge crew to medieval England, where Captain Picard is Robin Hood and the bridge crew are the Merry Men. English soldiers attack the group and the group retreats to the forest.
Q assumes the role of the Sheriff of Nottingham and has imprisoned Vash, now Maid Marian. Picard must rescue Vash as she is sentenced to die for treason. Vash manipulates Sir Guy of Gisbourne into sparing her life by professing love and promising marriage. Picard realizes that if he does nothing, Vash will die. He orders his officers to remain in the woods, then disguises himself and infiltrates the castle as a peasant worker.
Picard climbs up to the tower and through the window. The two bicker over the merits of Picard's rescue plan, and Vash refuses to go. Picard begins to carry her away when a group enters. Picard is taken away by the guards, and Vash tries to send a message to Commander Riker, which is stopped by Q, who reveals himself to Vash and has her taken away.
At the chopping block, Picard's officers reveal themselves disguised as monks and create a diversion. Picard and his staff prove themselves formidable fighters and win. Picard frees Vash, who leaves with Q to explore the galaxy. Q guarantees Vash's safety; with that, Picard considers Q's debt paid in full.
