You mean to tell me that this couple -- these folks we've never seen before, but who know Alfred and where "the house" is, an who Batman would "know anywhere"...
You mean they really are...?
Well, I'll be superamalgamated.
No explanation, just "Yep, we sure are dead. We don't look like us, and we don't even look like we looked last issue, and we are dead as dead can be, but here we are. Mysterious, isn't it. But it's true, Batman says so, and he's never wrong, except about that whole Brother Eye thing. So, how you been?"
Somebody's nose should be twitching, all right.
Disclosure: I edited the second panel, borrowing dialogue from the panel just before it, because it seems that DC has forgotten how to do a Dramatic Reveal. Don't they know the characters only say their own names in conjunction with a full-face portrait? Isn't this cast of characters confusing enough without having characters that intentionally don't look the same from issue to issue?
