( CNN ) -- No doubt about it , actor Steven Yeun is in a pretty great place in his career . He 's on one of the most popular scripted series on cable , `` The Walking Dead , '' and he 's one of the most popular characters on that series . On top of that , he is as close as one can get to being a romantic lead on a show about a zombie apocalypse . His character , Glenn , is involved with farmer 's daughter Maggie , and they have the most stable relationship of all of the survivors at this point . Of course , stability -- not to mention life itself -- is a very fragile thing on `` The Walking Dead . '' The third season , which began on Sunday to record ratings , sees the group settling in what at first appeared to be in an abandoned prison . Yeun spoke with CNN about the new season , the fans and what scares him more than zombies . CNN : Where is Glenn 's head at this season ? Yeun : He sees himself as , if not a leader , at least a provider and protector and someone to look to in times of trouble . You see Glenn in this moment ready to take up the charge . It 's not easy , but these are the moments he 's been preparing for . We 'll see how that plays out . CNN : How devoted is he to Maggie now , as opposed to the rest of the group ? Yeun : I think Maggie is his strongest link . She 's the sole thing he identifies with . I think she 's the only thing that keeps him from going off on his own . I do n't think he completely trusts the group . You saw in the last season , he questioned Rick , someone he 's always looked up to . Glenn saw that the only thing he can really trust is his own gut , and he needs to do that to protect the people he loves . Maggie is his sole connection to being in this world , even . CNN : What new challenges come with the change of setting ? Yeun : It 's an adjustment to get used to being on stages , not outside all the time . Luckily , our writers and producers make sure we had plenty of time in the battering heat . It was a challenge at first , but it 's fun to play how the situation changes how the character behaves . CNN : Is there anything for Glenn this season that tops that grotesque , harrowing scene in the well ? Yeun : This season is literally no holds barred ; it 's gas pedal down . I 'm excited for people to see what 's coming . It 's just crazy . The well was an amazing thing . It was terrifying and fun . There 's definitely stuff this season that tops that by far . CNN : How does it feel to know about the season premiere 's record-breaking ratings ? Yeun : It 's pretty damn amazing . It 's nice to know that people are anticipating it and telling their friends . It 's all around great . CNN : Are you into horror movies ? Yeun : I 'm not much of a horror fan . When it comes to ghost stuff and demon stuff , I ca n't watch that . I 've heard too many crazy stories about that stuff , so I do n't mess around that . Especially when you 're staying in a haunted hotel . CNN : So zombies are no problem , but ghosts on the other hand ... Yeun : Zombies -- you can deal with that . You can punch or shoot them . With ghosts , you 're going to be possessed , or something 's going to be thrown at you . You ca n't do anything about that . No , thank you ! CNN : Did you run into `` Mythbusters ' `` Grant Imahara when he dressed up as Glenn at Dragon*Con this year ? Yeun : That 's pretty amazing that he did that . It 's amazing to see anyone do anything with that character . I 'm just lucky enough to be able to play it in a public forum . CNN : Have you had any unusual `` zombie '' interactions outside of the show ? Yeun : People are strange sometimes , which is completely hilarious to me . A really normal couple in Atlanta were walking down the street , and the girl recognized me and started walking towards me in a `` walker '' walk . And she was committed , like `` Uuuuhh , I love your showwww ... '' That was unique . CNN : Finally , I have to ask , do you ever try to get information out of `` Walking Dead '' creator Robert Kirkman about what 's going to happen on the show ? Yeun : They 're pretty protective ( of that ) . They hold on to things sometimes . We just do n't ask , out of courtesy . And also , if you ask , you may put it on yourself . CNN : Do n't mess with the guy who could kill you off , huh ? Yeun : Exactly .
