Both “The Sopranos” and “Gilmore Girls” are grounded shows. The shows are grounded in real life and no supernatural events occur. Someone could write a sci-fi/horror spec about the Gilmores who are watching tv one day, and notice that the Gilmores’ experience is reflected in the TV series. The Gilmores would have a similar experience to Truman Burbank in “The Truman Show”, when he saw a spotlight falling from the sky. Someone would have recorded all their actions and transposed them into a separate TV series. Tony would be the same, hearing his own name on a television show and wonder why it’s important.
The possibilities are endless. Imagine if the two sets of characters were watching each other simultaneously. Would it cause a paradox, which could threaten to bring all the characters’ realities crashing down? It’s possible the only way to correct this paradox is to seek out a Nexus being existing in both worlds — the late, great Brian Tarantina. The actor appeared in one episode of “The Sopranos” — “Another Toothpick” — as Mustang Sally. He also had a recurring role on “Gilmore Girls” as Bootsy. The two characters in question must be the same character, just assuming different identities. The key might be in his hands to find a way of balancing the universes and preventing their worlds from ending when the horrific revelation is revealed.
Honestly, that’s the storyline they should’ve gone with instead of “Gilmore Girls: A Day in the Life.”
