Lana already died and plus the exchange was jonathan dying,.. so if i were clark if he really loves lana that much run the risk and tell her that again, Lana has to know the truth so that their relationship would work and after that Lana would UNDERSTAND again (is that right? she should freak out)... well as far as now at the current ep. they will break-up again bec. of the trust issues AND im sure it will be the last break-up I'll ever see on Clana... no more coming back on them I'm tired on them..
I would be glad if it will be CLOIS or chlark
