This week in television featured the return of some beloved shows and the finales of others. Sunday night began with an episode of Once Upon a Time that might have featured the most character development on the show to date. The night continued with another strong episode of The Good Wife and one of the most controversial episodes of Game of Thrones in the show’s history. Monday brought a lot of fun to our living rooms with “party anthem” night on Dancing with the Stars and a new Castle episode that took the characters back to the 1970s to solve a cold case. Tuesday’s episode of The Mindy Project served as a potent reminder of just how wonderful Mindy and Danny could be together, and Wednesday’s Nashville concert special featured the show’s best songs performed by its talented cast. On Thursday, the sixth season of Parks and Recreation ended with huge leaps forward for all of its characters, and Saturday’s episode of Orphan Black was yet another thrill-a-minute way to spend an hour.

From every scene with Regina on Once Upon a Time to Alison drinking with Felix on Orphan Black, there were a plethora of great moments to choose from this week. But the best of the best came to us courtesy of Parks and Rec‘s season finale. The conclusion of the Unity Concert, with all of the episode’s guest stars joining a reunited Mouse Rat and Duke Silver onstage, was a huge dose of the kind of positive energy that only this show can provide. The joy on each character’s face was a perfect representation of this show’s ability to spread happiness, and I’ve been singing “5,000 Candles in the Wind” with a smile ever since Thursday night.
