We don't know. Near the very end, after Blair got Chuck down from the ledge, Uncle Bass put a wasted chuck in the limo and Blair told him not to tell him about New Years. Whatever that meant... it made it sound like Blair and Uncle Bass slept together... Dan and Serena are not blood related, no matter what, so I do not see where the constant hang up is...
