( CNN ) -- Milton might be dead on `` The Walking Dead , '' but actor Dallas Roberts ( who portrayed the Governor 's one-time lackey ) is very glad to be alive -- and finally able to talk about the show 's season three finale . `` You ca n't imagine the pressure that 's finally off , '' he said . `` I 'm finally able to have all the cards on the table . '' Before Sunday night , Roberts had only told three ( OK , maybe four ) people about how Milton would become a walker , keeping the list limited to his girlfriend , his kids , and maybe a trusted friend who lived near where they shot the show in Atlanta . `` I may have taken an authorized photo of myself as a walker , and I may have sent that to him under threat of dismemberment if he passed that along , '' Roberts said . `` But the last thing you want to do is spoil season three of 'The Walking Dead ' where you turn into a zombie and kill Andrea ! '' Laurie Holden shares final thoughts on her 'Walking Dead ' experience . Turning into a zombie meant Roberts finally got his turn in the chair in the `` more bloody and gross '' makeup trailer reserved for walkers . All season long , Milton has been kept squeaky clean , raising serious questions such as , `` Where is he sending his dry cleaning ? '' Roberts laughed . `` How is he showering three times a day ? Where is he getting all his razors ? '' `` From the beginning , they were like , 'No sexy dirt on him . He 's always clean . He 's always tucked in , ' '' Roberts continued . `` I was like , 'Wow , there 's something about this that 's going to go somewhere . ' And nope ! He 's just the clean guy . No sexy dirt for me . Milton never got the sexy anything , did he ? '' But for the few scenes in the finale , Roberts was sexy , dirty , bloody , the whole shebang , as Milton was left in a locked room to turn and `` tear the flesh from ( Andrea 's ) bones , '' whether he liked it or not . That scene meant he got to go through a lot of emotional turmoil , `` knowing she 's going to be taken out , knowing it 's over , and everything he worked for is going to die , and someone he cared for is going to die . '' What 's inside a walker ? Cast , producer spill their guts . Milton did n't imagine that he would be `` used as a tool to take Andrea out '' as well , and if he had , `` he would have behaved differently , '' Roberts said . `` I think he thought there would be a bullet in his head , and that 's it . '' In the original plan for the scene , there actually was a bullet involved , but during the reshoot , it was changed to a stabbing . Either way , Milton had to collapse , he said , `` in a pool of fake viscous blood that sort of cooled and crackled for hours and hours and hours . '' To make shooting that part of the finale a little easier , his co-star David Morrissey kept him in stitches beforehand with some `` gallows humor . '' `` Before the door opened and he throws me to my knees , he and I were crying , laughing , at the jokes we were making , '' Roberts said . `` I can promise you that they were completely inappropriate , and that they were hilarious . After a while , it was n't even that it was funny as much as that we needed to straighten up before that door opened . It was like laughing in church , or laughing in school . '' But no matter how much fun he had on set , do n't expect Milton to be back in the form of flashbacks or visions a la Lori for Rick . `` I do n't think anyone wants the Governor to see Milton in a white dress on a balcony ! '' Roberts laughed . ( Plus Roberts just landed a regular gig on `` Unforgettable '' and remains a recurring guest star on `` The Good Wife . '' ) Besides , assuming he was on the outs , Roberts swiped a beaker that Milton used to use . `` I was n't going to take the clothes , for sure , '' he said . `` I mean , they were great clothes for Milton , but not for Dallas . Pleated khakis ! ''
