- This is the first SR season to be completely drawn with Pilot G-2 gel pens, which gives the comics a cleaner and more detailed look compared to the previous seasons which were drawn with various brands of generic pens.
- Season 1 was originally only going to be six comics long, with "River Rock Rivalry being the Season 1 finale and Season 2 starting with "The Flash Drive Complication". However, the latter comic, as well as the next comic "Restraining The Beast" were taken from Season 2 and placed into this season instead. Season 2 now begins with "In Loving Memory of Aiden McReary".
- The style of the cover (which is supposed to look like a yearbook) was taken exactly from that of the original Season 1 cover for The Wolves, which was a scrapped series by GTA Nerd that would have started in January 2017, but was scrapped due to the difficulty he had of bringing the series to life.
- Even though Victor always comes before Anthony when GTA Nerd lists the characters, on the cover they are reversed, which is a mistake.
- This is the first SR season that Angel Chacon is present for all comics, even though he usually appears in cameo appearances only.
- The only major characters from Sibling Rivalries to not return in this season are David Saldivar, Armando Vasquez, and Braulio Guillen, though David's voice is "heard" in "The Flash Drive Complication". Pablo Torres made a brief cameo in "Love At First Plight" but his face was not shown in this season.
- This is the third season after the original series's first and fourth seasons to have all of its comics released in only one year.
