If you’ve been scratching your head about where you’ve seen Negan from The Walking Dead before, the mystery has finally been solved. Denny, meet Negan. That’s right, the big, scary, monstrous Negan currently striking fear into the hearts of The Walking Dead fans is none other than Denny Duquette, the soft-spoken, endearing, dying love of Izzie Stevens.

Denny Duquette

Jeffrey Dean Morgan first won the hearts of Grey’s Anatomy lovers playing Denny Duquette from 2006 to 2009.

During his career from 1991 to present, Morgan’s longest run on a TV show has been Grey’s Anatomy where he appeared in 23 episodes. His character fell in love with Dr. Izzie Stevens, played by Katherine Heigl, while he waited in the hospital for a heart transplant. Eventually Denny passed away, but that was not the end of Denny's role on Grey's Anatomy. Morgan appeared as Denny in multiple episodes as a hallucination of Izzie’s while she was dealing with a brain tumor. Although Denny made his last appearance on Grey's Anatomy during season 5, the show is still going strong, currently wrapping up its twelfth season and it has been picked up for season 13.

Negan

While Jeffrey Dean Morgan has currently only starred in one episode of The Walking Dead, he is one of the most talked about characters in television history. Spurred by the stories in the comic books, fans are excited to see what Negan will do on the TV version of The Walking Dead. First introduced in the series by name only (by the way, did you notice he only has a first name?) during a prologue aired after the mid-season 6 finale, the legend of Negan continued to grow until his first physical appearance. The one time viewers saw Negan was during the season 6 finale of TWD. Negan held Lucille, his barbed-wire wrapped baseball bat, as he traipsed along a row of fan favorite TWD characters, deciding which one he should kill while reciting "Eeny, meeny, miny, moe." Fans were left with a cliffhanger, never finding out who the chosen one was, and will be waiting for months to find out when the season 7 premiere airs in October 2016.
