well obviously leviathans don't mind the extreme tortures that archangels dish out. and they are unaffected by angels and there is nothing to suggest that they are immune to archangels. cas is an angel, of course archangels can break him, and as leviathan sam is experiencing all sams thoughts and memories he should either be insane like cas (which hes not as he is highly functional) or is simply unimpressed with lucifers techniques which is impressive as lucifer was clearly excessive in his torturing methods.
