I admit seeing the tweet was a relief even though he's said before that he's not breaking them up and I have had no reason to doubt he's telling the truth. People have not trusted him, not even after (or rather especially because) of #1004 which wasn't well written. Lois and Clark may have to deal with issues separately like Sam and Jor-El but they aren't separating. Whatever change he's likely bringing to the books is Jon and who he is for the public.
