Here's what he said about the Lucille scene
"But something as well known as that moment — maybe it would seem like it wouldn’t be a great thing if we did an exact sort of thing just because people might be expecting it. All I want to say is, read the comic, but you’re not going to know what to expect. Part of the reason that that moment was such a big deal in the comic is the fact that you did not expect that it was going to happen, and so we’re very confident that we found a way to keep it as unexpected in the show as it was in the comic. So it should be just as intense, just as heartbreaking, and just as shocking."
