As “The Walking Dead” villain Negan, Jeffrey Dean Morgan has stunned fans with his wry turn as the brutal “big bad” of TWD Season 7. So it’s no surprise that he’s got a fan in Jensen Ackles who played his “Supernatural” son Dean Winchester to JDM’s John Winchester.

Jensen Ackles posts Twitter love for JDM

On October 27, “Supernatural” actor Jensen Ackles tweeted and IG'd speaking as his SPN character Dean saying “Hey Dad, you left something in the impala.” See the pic below of Jensen holding a barbed wire wrapped bat that’s an obvious shout out to Negan’s beloved and brutal bat Lucille.

Jeffrey Dean Morgan tweets back as papa John

Jensen tweeted another shot of the scary baseball bat on the hood of the Impala known as “Baby” on “Supernatural” saying “I found this in the trunk…can I try it out?” Then, he joked with bat in hand that tonight’s new episode of Supernatural is a “knockout.”

And then another rib tickling exchange from TV father and son...

The ever-clever Jeffrey Dean Morgan bounced back to Jensen on twitter saying “You weren’t supposed to find that. Gonna need her back son. I mean…I already gave you my car. And? I don’t know? Sorta, died for you.”

The Supernatural family hangs tight

For those that are fans of “The Walking Dead” that haven’t dipped their toe into the “Supernatural” pond yet, it’s worth a try. Jeffrey Dean Morgan brought the same tough-but-funny-guy sensibility to the role of Negan that he had as SPN’s patriarch John Winchester and as The Comedian of The Watchmen.

The “Supernatural” gang seems to be a tight crew. Show alums that are dead and gone still show up to Supernatural conventions, even those that weren’t on the show for too long.

Two former “Supernatural” actors are now together on “General Hospital” – James Patrick Stuart and Matt Cohen.

They both attend the events and Matt Cohen is a regular on the Supernatural karaoke event alongside Misha Collins who plays down-to-earth angel Castiel. One thing is for certain. The affection Jeffrey Dean Morgan shared for on-screen son Jensen Ackles seems genuine and has transcended “Supernatural.”

Fans are still reeling from the deaths of Glenn and Abraham on "The Walking Dead" season 7 premiere but new TWD spoilers show two more kills will come from Negan in the Season 7 Episode 8 mid-season finale. 

“Supernatural” airs Thursdays on The CW and “The Walking Dead” airs Sundays on AMC.
