Not have a new arrowhead as the official title card. Additionally, the opening title card for "Fadeout" featured all the arrowheads from the previous title cards lined up together to form a crown very similar to the title card from the SDCC trailer.
Although Katie Cassidy was credited in the "special appearance by" bill, she was still considered to be a main cast member, according to TVLine.
The first seven episodes featured all of the title cards from the first seven seasons in order.
Whilst this season didn't have a traditional "Big Bad" like preceding seasons, the Anti-Monitor, who was heavily foreshadowed and referenced throughout the season, is the overarching antagonist and can be considered as the "Big Bad" of the season.
Grant Gustin and Melissa Benoist were also credited in the special appearance bill in "Fadeout".
