The Truth of Unus Annus

Summary
Following up from the ending of the last episode, the Unus Annus crew is heard laughing inside the abandoned house, wrapping up their shoot for the night. As Ethan's washing up, his walkie-talkie begins to pick up a signal from what initially appears to be Mark exclaiming "It's time." Moments later, the lights go out in the entire building. As Mark and Ethan etch closer to one another in complete darkness, they begin to hear their own voices addressing them through the coms, stating that their time is up. Despite the two pleading for another chance to better themselves, the disembodied voices note the end is upon them and that they have to accept the "truth."

The scene then cuts to a shot of a coffin, with Mark and Ethan approaching it from each side. As they open up the casket, a sped up transparent compilation playing Unus Annus videos in reverse overlaps across the screen, with the final showcase concluding on the channel's first video. Fischbach and Nestor close the casket to reveal their Unus and Annus personas in their stead, as the two walk up towards the center of the room and exclaim "It's time to say goodbye. Memento mori. Unus Annus."

Trivia

 * The intro features a stop motion animation by Cranbersher, albeit without the accompanying outro sequence seen in the two preceding videos. Cranbersher's opening is also the only one that's been featured three times on the channel, as oppose to GrittySugar and UltraMarine's works that were shown twice.
 * The intro opens up to a table featuring three large Unus Annus-themed items. In the center lies a ticking timer with the channel's continuous black and white spiral layered on top of it. The carving on the clock's rim reads "MEMENTO MORI." To the left of the timer lies a closed casket and an hourglass on its right, with white skulls inside each glass cylinder and an engraving on its base that reads "Memento Mori, Unus Annus."
