Book Ends/Web Animation

Note that some Book Ends can be spoilers, so beware.

Examples of Book Ends in Web Animation include:

Red vs. Blue has one of the three possible endings as an inverted book end—whereas Episode 1 features the Blues spying on the Reds, who are chatting atop the base, here we have the Reds spying on the Blues doing the same thing.
- This is also the canonical ending.
- Grif and Simmons also once again call shotgun on the new vehicle, this time in reverse.
- This happens again in the Recollection Saga. Reconstruction began with a soldier looking at the dead body of a Freelancer as the camera panned up in Valhalla, showing a huge number of characters (so many that the creators actually had to run several games and use splitscreen to get that many). Revelation ends with a soldier looking at the body of Agent Texas in Avalanche and the camera pans up to show a similar shot.
The first scene of There She Is is Nabi being harrassed by Doki at a drink machine. The final scene is Nabi wiping racist graffiti off of it while sharing a drink with Nabi.
The Strong Bad E-mail "theme song" from Homestar Runner actually begins and ends with Strong Bad singing "When E-mail Comes to Town, It's Like a Rainstorm in your Browser."
Bowser's Kingdom episode 1 ends with Mario beating up Hal and Jeff because a Shy Guy betrayed them and The Movie ends with Mario and Luigi beating Hal and Jeff because Steve betrayed them.
