A Thread 
1: Mark and Ethan will end it off with a live stream. With a live timer at the corner. Again inspired by the person tagged, it will start with a pre recorded video of Unus and Annus saying their final goodbyes.
2: Take suggestions from fans of what they will do if they have a livestream. Small suggestion for videos they weren't able to do.
3: Speak about unreleased videos, with Amy and Evan.
4: Talk about the guest that they had in Unus Annus. Hopefully bring maybe Alex for a couple minutes. Either in person or over a video call.
5: Look at fanart from the fans, which would really make my heart go soft. 
6: Make Unus Annus trend on Twitter.
7: Look back on old videos that were their favorites/least favorites.
8: Maybe play some video games.
(Again this is if they end it with a livestream)
9: Talk about the theorist and our theories. The two denying about lore of Unus Annus.
10: For the last 30 minutes to an hour. They sit down and talk about saying goodbye. Have a chat with some fans over a discord maybe?
11: Mark and Ethan delete the website and other sources before deleting the channel.
12: A final goodbye, Mark and Ethan probably getting emotional. The livestream ends with the two saying
"Unus Annus."
"Unus Annus."
13: The screen goes black and we see the timer hit zero. The livestream ends. Minutes/Seconds later the channel is deleted.
14: (If they don't end it with a livestream) A short video with Unus and Annus saying their goodbyes. That's it.
15: A video sort of like "Hunting HeeHoo." With narration and amazing camera shots!
16: Maybe a teaser/trailer for any upcoming projects Mark or Ethan have planned!
That's all for this thread! I'm pretty sure they'll end it with a livestream. #UnusAnnus @UnusAnnus
