For a few issues they were teasing "The Snowman's Ticket" and revealed him to be a previously unknown brother of Lois Lane, Leonardo Lane. In the 6th issue they used the caption "The Daemon Rose" as his title, and that was the only time it appeared other than the covers. Bendis also kept making Lois and Clark say how much he looks exactly like their son Jon..... which is not how genetics work I'm pretty sure....
The series ended with Leviathan killing off Mark Shaw and Talia Al Ghul taking it over, bringing everything in full circle and making everything with Mark Shaw pretty pointless
