User blog comment:Tommy,Klaus&Kol2012+/How to Kill a Levithan/@comment-4860000-20120225124919

I think we'll have to wait until Castiel returns to see if they are truly so powerful as the writers have made us beleive they are. It is quite possible that angels are equally strong as the leviathans. And even if Leviathans are stronger they still cant kill an angel because they dont got any weapons that can kill them either. And angels can most likely turn the leviathans vessels to dust, but Leviathans cant do that to an angels vessel. I believe that the angels will be the answer to how to destroy the Leviathans in the season finale.
