I hate those jinx threads. Seriously, I do. For your information, serena won't make it to the final. You can take that to the bank.
And to answer your question, if by some unfortunate and unlikely incident Kim was forced to withdraw from her match against serena (the only way serena would make it to the final) and serena plays justine in the final, ofcourse justine will spank serena (I sense a double bagel in this match). But, all this is unlikely. Kim will make it to the final.
You can take that to the bank, too.
