 It 's something that 's very difficult for me . Because it is lines on paper when I do it in the comic book series . It 's like , ' Oh , okay , Charlie Adlard [ ... ] doesn ’ t have to draw that arrangement of lines anymore , that person is dead . ' But it 's very uncomfortable for me to be on set , because I see these actors that are there and , in the source material , I have killed all but two of them . I walk through the set and I 'm like , ' Yep , killed that one , killed that one , killed that one . ' And it is firing those people . I feel really bad for Emma Bell , just because she was great and I would have liked to have had her in the show . But , you know , this is The Walking Dead , characters have got to die . Thankfully , Emma was brought onto the show with the understanding that she was only going to be in a certain number of episodes and she knew that she was going to die from the very beginning . But it doesn ’ t really make it any easier . When they were shooting those scenes , I had to fly to Comic @-@ Con and so I wasn ’ t actually there for when she died . But it was very emotional on set and I know that she was very upset about having to leave the crew and the actors . You kind of become a family when you 're doing a TV show and it ’ s a little upsetting to have to get rid of somebody .
