At a Supernatural convention in June, Jared Padalecki revealed some new Gilmore Girls info regarding his character, Dean.
Padalecki said that he has one scene with an actress that was working every day (presumably Alexis Bledel) in the market.
Dean’s departure from the show was abrupt and fans of Rory & Dean, including Jared himself, never got closure with that relationship.
It seems that this revival scene does a good job at wrapping up that story nicely for both characters!
