Who's the Daddy?

What's going to happen now that this has all blown up when it comes out that Daniel really is the Daddy?  Maybe someone at the hospital really did make a mistake and Caroline changed it before it could be corrected by the hospital lab techs..............stranger things have happened on this show------you just never know.................

P.S.  Do you think Lucas really is Johnny's father?  I sort of expected something to come out during his eye surgery fiasco about his blood type....would have been a perfect time to bring that story line out.
