Nothing would happen because she knows that Clark and her can never be together, that's why she left. Besides I would think she already knows. P.S Clois FOREVER!!!!!!!!!!
haha I know she would be happy but, what if she was like "What?" "Your getting married to the girl आप used to call annoying and talked to much?" "Huh a lot must have happened when I was gone...." लोल I wanna c that now! :p
She probably would have acted in typical Lana fashion. "I'm happy for आप Clark. Lois is a great girl. आप deserve happiness. I always knew there was something there..."
I Think that if Lana found out Clark and Lois were going to get married? She would be happy for him because she already knows her and Clark cannot ever be together again because she is full of Clarks weakness that ='s krytonite. Plus she already told Clark in the Bride episode Season 8 Lana: Maybe Lana Lang and Clark Kent just weren't meant to end up together. So She already knows each time they got together they were going against fate. Clarks True Fate is with Lois Lane.. *Clois is Forever*
