User blog:General MGD 109/Leviathan powers, subpression or immunity?

Okay the point of this blog, is a lot of users are stating that Leviathans can supress angels powers, evidenced by the scene in "Reading is Fundermental" where the second Angel's counter attack, has no affect on Edgar. However I think your wrong, and Leviathans can't supress Angels powers, they are simply immune to them, much like how Sam was immune to demonic white light, or all those other demonic powers.

For Starters, appart from that incident we have had no other evidence they can supress angels powers, Castiel was able to teleport around Roman industries, despite all the Leviathans around, and he still had his superhuman strenght, as evidenced by him temporarily being able to restrain Dick Roman. Likewise in "A Little Slice of Kevin" Castiel's powers still work when confronting the leviathans in Purgatory, and he is even able to hold his own against them for a short while, if they can supress Angels powers how could he do these things? And is it really belivable they can only supress one angel power? I very much doubt it.

Any way that is my argument, I await any opposers counter arguments.
