That the borders of the comic since the start of this arc have been jagged when they're around the mirror and the boxes? AND ONLY THE MIRROR AND THE BOXES? (Okay, so this last page has shown the border change to being completely jagged, which tells me that our heroine is toast come Wednesday. Or of course we'll simply get the Raven next panel (Darkness there, and nothing more) and then Kain will come out and stab her from the mirror! Bwahahaha!
Anyway, just wanted to point that out, shoulda been a hint if I'd noticed it earlier!
