Blindspot / 8:00pm (4) The past becomes the present for Jane and Weller (Jaimie Alexander, Sullivan Stapleton) in the drama’s Season 3 finale, “In Memory,” as their pursuit of Roman (Luke Mitchell) leads them back to very familiar territory. David Morse, Gloria Reuben and Tori Anderson reprise their guest roles.
MasterChef / 8:00pm (5) At least one youngster is sure to leave this show very happy as the finale of the show’s sixth “Junior Edition” closes out the competition’s season. Three finalists prepare for their last culinary challenges as the two-hour presentation begins, with a three-course meal as the centerpiece of their concluding test. Host Gordon Ramsay and fellow judges Christina Tosi and Joe Bastianich gauge the results and declare the winner.
Once Upon a Time / 8:00pm (7) The fantasy-drama series ends its seven-season run with the appropriately titled “Leaving Storybrooke,” which should indicate the fates of characters who have been with the saga from its start, as well as more recent additions. Of course, it helps to remember that on this show, nothing necessarily lasts forever — though it appears, at least for now, that its cancellation will. Former cast members Jennifer Morrison, Ginnifer Goodwin, Josh Dallas and Emilie de Ravin return for the finale. Alison Fernandez, Dania Ramirez and Andrew J. West also star.
Hawaii Five-0 / 9:00pm (13) The Russians are coming ... and it’s not a movie title but the fact in the case of “Waiho wale kahiko” (Hawaiian for “Ancients Exposed”), the crime-drama reboot’s Season 8 finale. A foreign submarine turns up near Waikiki, alerting McGarrett (Alex O’Loughlin) and the team to the presence of an overseas originated spy operation in Oahu. Tani (Meaghan Rath) is unsettled by her discovery regarding Adam (Ian Anthony Dale).
Alison Fernandez, Dania Ramirez and Andrew J. West (from left) star in “Once Upon a Time” Friday on ABC.
