The problem was that it appeared that killing Chloe would have been the only way to defeat him,but with the help of his cohorts from the future, Clark was able to find another way to defeat Brainiac.Meanwhile Davis was turned into a full blown “Doomsday” monster.
I’m really curious to see what Davis / Doomsday is going to do next. I’m totally into this season’s “Smallville” now after it having a semi slow start.
