After Glenn (Steven Yeun) and Maggie (Lauren Cohan) spent most of the second half of "The Walking Dead" Season 4 trying to find each other, Yeun thinks that the couple is now inseparable.

"I think they're solid. I think they're sound. I think nothing's really gonna get in between those two," the 30-year-old Korean American actor said of Glenn and Maggie in an interview with Entertainment Weekly. "I think we established that very well in their journey last season."

The "I Origins" actor went on to explain that the moments the two characters spent separately in Season 4 also made them stronger as individuals.

"I think that journey also solidified in them individually, the idea of searching for humanity, of holding out hope that in spite all odds that there can be salvation," he explained. "If the goal last year was to do the impossible by finding your loved one in what was probably the most dangerous situation, and the most impossible situation, and they accomplished it - then, I mean, what else can't they do, you know? And I think to them individually it's been a really great growing lesson, for the both of them and also individually."

At Fan Expo Canada in Toronto last August, Cohan opened up about why she thinks romance is important for Glenn and Maggie.

"At least for the character, it helps keep you sane," Cohan said of the romantic relationship between the two characters, according to Comic Book Resources.  "It's so funny. Even during the show, you need a hug a lot of the time from the emotional [strain] that it is. It is important to see these things and that people find love."

Meanwhile, since the first trailer for Season 5 was released at San Diego Comic-Con in July, fans have speculated that Glenn may face his horrendous death in the upcoming installment.

In the comics, Glenn is beaten to death with a barbed-wired baseball bat, while his allies are left with no choice but to helplessly watch their friend's demise as they are all tied up, The Wrap reported.

When E! News asked Yeun to comment on the rumors, the Seoul, South Korea-born actor took a deep breath before answering.

"Ugh, I mean... sometimes it's rough, I mean sometimes it's awesome. We will see what happens, yeah."

"The Walking Dead" Season 5 premieres on Oct. 12 at 9:00 p.m. ET on AMC.
