'Walking Dead' Actor Danai Gurira on Season 7 Premiere: 'It Was Horrifying'

— -- Warning: Spoiler Alerts

After last season's gut-wrenching cliffhanger that left us wondering who fell victim to Negan, fans finally bid farewell to not one, but two heroic favorites on Sunday’s premiere of "The Walking Dead."

Danai Gurira, aka Michonne, stopped by "Good Morning America" today to discuss the shocking outcome, plus the aftermath of saying goodbye two beloved cast members on the show.

"The heart and soul of the show, to lose them, I thought it was very important to see and to feel that loss because that loss transforms everybody," Gurira said. "It's devastating and I thought it was beautiful that we walked through it together, though it's the most horrible thing to walk through. ... Everyone's response is utterly valid.

She added: "It was horrifying to sit through that experience … the transformation that it causes us as a group couldn't really have been experienced unless you walked through that experience with us."

Sunday night's episode revealed that Sgt. Abraham Ford (Michael Cudlitz) was the first to fall victim to Negan's bat, "Lucille," after being chosen in "eeny meeny, miny, moe" fashion.

Glenn (Steven Yeun) was next after Daryl reacted to Abraham's death by punching Negan in the face.

"Maggie, I'll find you," were Glenn's devastating last words to his pregnant wife, Maggie.

Gurira said the audience will see a change in her character, Michonne, in the wake of both characters’ deaths.

"The loss upon loss and then what almost happens to Carl, to her it was the most devastating thing because she's doing the math as she's sitting there," she said. "She cannot help in any actual way. She tries everything she can do.

She talks to Negan and tries to talk him down, which she's the only one who tries that tactic because that's how desperate she gets. But there's no way around it and to be that disempowered, and that helpless to her this is a woman who gets up and gets it done."

At the end of season 6, Michonne develops a romance with the group leader, Rick Grimes.

Gurira said the introduction of Negan as the show's newest villain could affect the relationship between Michonne and Rick.

"We'll have to see what the aftermath will be for these two," she said. "They are very much in a committed love-filled relationship. They fell in love as best friends but they are in a moment of complete and utter transformation and what will happen as they pick up the pieces. Nothings the same.

“This man [Negan] has changed everything. He's walked in their lives and everything they knew and everything they thought they knew is completely transformed."
