Heartwarming Moments: Resident Evil Numa REmake eventually starts showing animations of characters dancing. In particular an adorable one is shown with Rebecca and Billy at the 2:55 mark, after they dance Rebecca hugs him. Not to mention at the end, the video shows certain characters (popular ships) happily paired together, which in turn gives warm fuzzies.
The author had uploaded a video in 2007 and used to joke about how Alfred's grandfather was named Grandpa Google and how he would eventually destroy YouTube. A few years later, turns out she was right.
An in-universe example in Teh Stream game, the author jokes about how one would play the original Resident Evil and imagine that, someday, they'd make a sequel about an alien invasion in Africa.
Ada Wong: The Worst Spy Ever pokes fun at the fact Ada uses her real name for every mission, and this ultimately blows her cover. A few years later, Ada works as a spy again in Resident Evil: Damnation, guess what happens when she loudly announces her name is Ada Wong.
Many who have seen Ada Wong: The Worst Spy Ever will often show picture of Ada's face once somebody mentions her full name online.
Moe: Just about everyone, thanks to the art style.
They Changed It, Now It Sucks!: Older videos used to be made with Paint and Windows Movie Maker only, videos before the author's return in 2013 used to be made with the same tools plus a little bit of Photoshop. Once she returned in 2013 with a brand new style and changed her animation tools to Sony Vegas and hand-drawn animation, many were displeased and stated her old style to be better.
