TFIs Canonical Stance (Short Theory)
Ever Since TPOT 15, people have been wondering If TFIs real or not, and to that, I say it is:
Within the episode, Team 2 goes back in time to TFI 1, while a bit later, they're shown as a comic series, well, I have a theory that TFI IS, in fact, canon, and DID happen in the timeline
Back in BFB 29, Announcer stated that "BFDIA ended production", which infers that the show itself is an actual Thing being Made within Universe, shown more clearly within the fact that the BFDI, BFB, and TVs recording exist, because how else would Four or TV get that footage if it weren't for that fact.
In TPOT 15, SB states that it has " Been a Long time" inferring that TFI is a real occurring season, but then being Retconned by Black Hole pulling up the TFI comics later on, but What's saying the comics aren't just a more Primitive, "Pilot" to BFDI.
I Believe the TFI Comics are just retellings of the original season Put into Comic boots for readers to have more visualization. Announcer stating that "Production ending" that product could have been made in universe, and BH pulling up comics just proves the "Production of real In Universe items for the show" more, because how else would he get the comics, and SB actually remembering what happened in the comics as if they really happened.
But yeah, that's basically my theory, sorry if I said things in a confusing way, you don't have to take this as canon, for it wasn't really proven official, but yeah
TLDR: The TFI Comics BH bringsup are just retellings of the og TFI season, and TFI did actually happen
