Here we go again. This isn't something that we "think" would happen, this is very much official information. Let me put it in yet again another way. Leviathans can kill angels. Angels = [Archanhels, Seraphim, Reapers, Rit Zien, Cherubim]. Therefore, Leviathans can kill [Archangels, Seraphim, Reapers, Rit Zien, Cherubim]. It is that simple, stated on the show. Something doesn't have to appear directly onscreen to know it is true. That's like saying Jody Mills can't be smote by an a angel, because it hasn't been directly said onscreen.
