With Supernatural already in its eleventh season, the drama has plenty of room to poke fun at other hit dramas. Its longevity has allowed stars like Jensen Ackles and Jared Padelecki make some hilarious pop culture references, but their target tonight was a familiar one. Tonight, Supernatural debuted its latest episode “Somewhere Between Heaven and Hell,” and the story kicked off with one massive easter egg for fans of The Walking Dead.

Yes, that’s right. Jeffrey Dean Morgan may have left Supernatural seasons ago, but his memory remains on-set. The actor may have joined The Walking Dead to play the drama’s ultra-violent villain Negan. However, to the Winchester Brothers, Morgan is still their father - and the boys are fans of his newest toy.

In the opening shots of tonight’s episode, fans watched as Dean strutted into frame with a familiar weapon. The man entered a bunker of the Men of Letters doused in blood, and a barbed-wire bat was slung from his hand. Of course, the weapon has become a popular one as of late thanks to The Walking Dead. The AMC series brought Negan to life, and the character’s weapon of choice is a wired bat called Lucille. And, when Dean mentioned their father loved the bat he was holding, fans promptly lost it. In the past, fans have wondered whether Morgan would ever consider returning to Supernatural following his leave. After all, the show does have a knack for bringing back fallen characters time and again. Speaking to TV Line, executive producer Andrew Dabb said Supernatural would welcome back Morgan if the star ever wanted to be a Winchester again.
