The tweet referenced a previous episode when Luke's daughter, April, discovered Luke was her biological father through a science fair project she conducted. However, the new image was cleverly altered to show different possibilities -- specifically, the different men who could be Rory's baby daddy.
Gilmore Girls: A Year in the Life memorably ended with Rory revealing to her mother, Lorelai, that she was pregnant. However, the father of the baby is unknown given that at the time, she had an open relationship with her ex-boyfriend, Logan, had an underwhelming boyfriend named Paul, and also had a one-night stand with a man dressed in a Wookiee costume.
"Where's an eighth grade science fair when you need one? #GilmoreGirls," the tweet read.
Sherman-Palladino told TvLine earlier this month that fans shouldn't hold their breath for more new Gilmore Girls anytime soon. "The old adage is you always want to leave them wanting more," she said. "You don't really want someone to walk away from something you worked so hard on going, 'Alright. I can move on.'"
However, she didn't quite close the book on more episodes.
"We pitched this as close-ended," she also told The Hollywood Reporter. "Netflix and Warner Bros., we all went into this sort of saying that this was it. So there really haven't been any more discussions about: Is there going to be anything else? I don't know."
