If Thor had done something bad enough to lose Mjolnir then he would have known it when it happened because it's part of the enchantment on Mjolnir , the enchantment doesnt need Nick Fury telling it what Thor did wrong or act as a messenger to Thor.

I've said this more than a couple times, if there was something Thor did that would make him unworthy it wouldn't matter if he was aware of it, he'd simply be unworthy at that moment. And you may want to watch the language before any mods see it.

The Whisper was just "instant" P.I.S. to allow Aaron new creative decisions (Female Version of Thor)... We shouldn't lose more time with this, will never make any sense...

It's not worth the stress debating it. Besides, there's a whole thread dedicated to the Fury Whisper of Doom. Any rational observer can realize it was a painfully forced plot-device. How bad? So bad they've yet to even hint at addressing what it is Fury did say (which ultimately doesn't matter).

I'm really beginning to think it will never be addressed with the current Secret Wars nonsense... "whisper? what whisper? that never happened... and fem Thor is the only Thor... enjoy..."

The enchantment on Mjolnir would be aware if Thor had done anything that would have lead to Thor being unworthy , so instead of Fury telling Thor something later and then Thor losing Mjolnir what should have happened is that as soon as Thor made a mistake , then the very next thing to happen after that would be the enchantment on Mjolnir preventing Thor from wielding it. The enchantment on Mjolnir doesn't need Fury to tell Thor at some later time that Thor made a mistake the enchantment on Mjolnir would have done that by itself, and right after that Thor should have known he made a mistake.

This is why the whole idea/story is so ridiculous and it is even worse when you consider that in the time that the "Fury unworthy event" occurs that it is after Thor has been through so many trials and been tested in so many situations to prove his courage and honor , Thor isn't a brash young Viking anymore so even the idea that Thor could screw up so bad as lose Mjolnir is pretty far fetched. So between the screwed up way Aaron treats the enchantment on Mjolnir and his ignoring the character Thor history it's all just complete nonsense.

you just gotta love the way how worthiness works........

sometimes it does and sometimes it doesn't......
