Multi-Part Episode

Sometimes, an episode is so long that it has to split into multiple episodes via a Story Arc. Long Story Arcs are usually the perfect reason multiple parts would work. The episodes' titles are the same, except the phrases "Part 1" and "Part 2" will be added after them. For example:


 * "Episode Title: Part 1"
 * "Episode Title: Part 2"

Also, at the end (probably a Cliff Hanger) of the first part, a message reading "To Be Continued" will appear on the screen. This means the rest of the story is saved for the second part. And the second part will always begin with a "Previously On..." montage that contains footage from the first part.

Type 1: The episode is split into two parts.

Type 2: The episode is split into more than two parts.

A multi-part episode is used when a given plot development is, quite simply, too big for one time slot. It commonly shows up in the Pilot Episode because that has to establish the entire setting, and the Season Finale because producers like to make a given year go out with a bang to help secure financing for another year.

Live Action TV

 * NCIS has quite a few of these for season finales, i.e. "Hiatus", "Kill Ari", etc.
 * Case in point, although rarely dubbed "Part 1 & 2", the only two-or-more-parters in The X-Files were the ones that dealt with the Myth Arc. In fact, after season 1, standalone mythology episodes became very rare.
 * The Six Million Dollar Man and its related shows loved this trope and wanted to have its children.
 * The Six Million Dollar Man. Of its 96 episodes, 20 were two-parters: "The Bionic Woman", "The Return of the Bionic Woman", "The Secret of Bigfoot", "The Return of Bigfoot", "Death Probe", "Sharks", "Deadly Countdown", "Dark Side of the Moon", "Return of the Death Probe" and "Date With Danger".
 * The Bionic Woman (1976–78). Of its 58 episodes, 14 were two parters: "Kill Oscar" parts 1 and 3 (part 2 was an episode of The Six Million Dollar Man), "Jaime's Shield", "Doomsday is Tomorrow", "Deadly Ringer", "The Bionic Dog", "Fembots in Las Vegas", "Welcome Home, Jaime"
 * The original 1970s Battlestar Galactica. Of its 24 episodes, 8 were two-parters: "Lost Planet of the Gods", "Gun on Ice Planet Zero", "The Living Legend" and "War of the Gods".
 * Star Trek: The Next Generation liked to do two-parters as season-ending Cliffhangers: "The Best of Both Worlds" (seasons 3/4), "Redemption" (seasons 4/5), "Time's Arrow" (seasons 5/6) and "Descent" (seasons 6/7). It also had the two-parters "Unification" in Season 5, "Chain of Command" and "Birthright" in season 6 and "Gambit" in season 7.

 * The CSI franchise LIVES on this trope for its season finales. The later seasons have nearly all ended on a dramatic note that audiences must wait until the next season to see resolved. Probably the most notable example were sesaon 7 and 8's "Living Doll/Dead Doll" and season 9 and 10's "For Gedda/For Warrick" pairing. The original series has also had at least two notable season finale two parters, season 5's "Grave Danger 1 and 2", as well as the season 6 finale "A Bullet Runs Through It". Sesaon 7 then opened with the two part "Built To Kill". Season 10 had Grissom's departure in "19 Down"/"One to Go". Catherine's departure in season 12 had "Ms.Willows Regrets"/"Willows In The Wind".
 * Merlin had four: 'Beauty and the Beast' 1 and 2,'The Tears of Uther Pendragon' 1 and 2, 'The Coming of Arthur' 1 and 2 and 'The Sword In The Stone' 1 and 2. The last two were the season 3 and 4 finales.
 * Buffy the Vampire Slayer had What's My Line 1 and 2, Bargaining 1 and 2,Becoming 1 and 2, and 'Graduation Day 1 and 2'.
 * Highlander 'Counterfeit 1 and 2', 'Unholy Alliance 1 and 2' and 'Finale 1 and 2'. Two other sets also qualify, though they were not a 1 and 2 case. The eps were 'Comes a Horseman' and 'Revelation 6:8' and the series finale, 'To Be' and 'Not To Be'.
 * This was frequent in The Lone Ranger, usually ending with "Will the Lone Ranger triumph as he fights on for justice, law and order? Tune in next week when General Mills brings you another exciting episode of 'The Lone Ranger' "
 * Tracker Fever Of The Hunt 1 and 2.
 * The Golden Girls had a few, including 'We're Outta Here' 'the Very Special Episode 'Sick and Tired',and the series finale, 'One Flew Out Of The Cuckoo's Nest'.
