Nib,
Problem is, as I've illustrated you're trying to have it both ways, and it's impossible to have it both ways. Think about the situation you illustrated in your post above.
Boxer throws a punch, lands on foes head improperly... You tweak your wrist. On one hand you say, well if your adrenaline is going, you may not express pain the way one normally would and just "tank through it". Okay, but for Ozy for fall over and be "stunned" as you call it.. that by default means his adrenaline wasn't pumping to that degree. So where you're trying to have the same sequence both ways?
On one hand you're trying to say his adrenaline was going so hard that is likely why he expressed no pain. But in the same sequence you go, well he was stunned enough that he need to say down for a moment and catch his breath. When you exhibit this adrenaline rush you're referencing ( I've experienced this in boxing and basketball you don't stay down.. close your eyes and catch your breathe. You continue to play and "fight" through it as you state. Then later you're like OH shit. Yet here, he didn't just fight through it did he.. yet your explanation for him not expressing pain is that his adrenaline was pumping so hard. See where I'm going with this?
To go further, even in the adrenaline situation... there is still pain... when I twisted my ankle and kept playing in the game (happened numerous times)... I didn't just hurt my ankle and not even make a sound or expression. I clearly indicated I was hurt... grabbed my ankle... sometimes said something... tied my shoes laces tighter.... and hobbled around a little bit till I could loosen it up and get the blood flowing again. Even then, I guarantee in your basketball situation... you should visible signs of being hurt directly after it happened.. and it even continued through the game no doubt. Which is the point here. Ozy expressed no such emotion like that.
My problem here is the double standards you're trying to use to justify your theory. Again, on one hand it made sense for him to take that chance, and in another it made no sense so you're dismissing it that premise. When in fact, the one you're dismissing much VASTLY more sense than the other. Think about it these...
Risk assessment
Preface - You freely admit he could've disarmed her before she could fire considering his other movement and speed feats
1. Stand right in front of an skilled armed foe. Decide to catch a bullet that is meant to kill you. I don't buy the dodge thing. Why catch it then if you can dodge it. Why catch something that according to you would stun you? You wouldn't. He had to catch it because she shot was meant to kill him. Just like in the book. It just moved so fast it looks like he dodged it to. Anyways, that is the unneeded risk he took
or
2. Act like you just got fatally shot... fall down... not make a sound... and have your eyes closed... while somebody still has a gun.
One is exponentially more of a risk than the other. One you're purposely exposing yourself to getting shot in the hopes you're fast enough to catch a bullet. The other, you might not get shot at all using a tried a tested deception tactic commonly used all the time. So no, I buy no assertion that no. 1 was less of a risk assessment than no. 2 That is totally illogical and implausible imo.
What's worse though... how can one, seemingly a bigger risk, be okay to do and plausible, yet another, you go nope I don't buy it. If you believe Ozy is prone to taking risk and chances.. well then Ozy is prone to taking risk and chances. How can you, with a scene lasting all of 25 seconds.. go well here in the first 10 seconds I can totally believe him taking a bigger risk.. but the final 15 seconds, nah, no way I don't see him taking that risk?? That just makes no sense to me.
To further prove one is a bigger risk. Ozy has intimate knowledge of SS and her psyche. He's the smartest guy on the planet. This means, not only is he using a tried and tested theory to deceive your foe... he would even further have an idea it would work just knowing Ozy. It's his job to know.
Real quick, the reason why the nature of the issue isn't important. Is because we see 100 different hand injuries and they generally always act in a manner I described. Holding their hand.. shaking their hand... showing pain on their face.. verbalizing said pain... grabbing their arm because their hand hurts to much to touch... all these and others are typical reactions we routinely see. I never seen anyone, receive any type of trauma to their hand... and act like Ozy did. It's simply not typical. Which was the point of the paragraph. I don't choose to side with maybe he's the exception to everyone. That isn't the most sound logical deduction to make.. so I choose to go with what is more likely i.e.
he wasn't really hurt that bad at all or stunned enough that he couldn't react. He simply wanted to play dead to gain the advantage again. Which is exactly what he did. I'm not sure if you answered this.... you mentioned where he disagree... i.e. him being stunned. So you're saying... he was so stunned that if they tried to punch kick him when he fell down that he would've been unable to react? I guess I'm looking for how "stunned" you believe him to be
