Random Thoughts.....What Are You Thinking?

That's not how that works. If it did then the same slow down would have occurred for Black Panther since he also has a healing factor. All that said, healing factors can only effect physical injuries which I find hard to believe this was. It was more of a... magical/instantaneous thing.

While I'm willing to label it as believable even that part seems like a bit of a stretch. Since the Spidey sense isn't some all powerful third eye sort of thing, it's really just enhanced reflexes/instincts/microcalculations and as far as I remember has only ever been triggered by things that can be avoided/sensed normally. The act of simply "Disappearing" doesn't seem like something that would trigger such a sense.

Given everything that happened in that scene I'm more prone to believe that he was just generally feeling like ***because of the loss of the previous fight and being around long enough to see 3 others just disappear before him.

Best case scenario I could see the stress of the situation causing his sense to multiply the negative feelings already present, sort of like regular anxiety. I think even if he hadn't been affected that he would have reacted the same way and thus that scene is more about a boy dealing with "adult" superhero problems.

I think you underestimate how powerful a lot of micro calculations can be. Particularly when paired with someone with super human senses. It becomes near precognition on a local scale. With enough information and processing power you can predict almost everything in theory and we already do a lot in more mundane ways. A rather simple way would be already knowing what Thanos intended and seeing others disappear in front of him he got enough information to figure out if he would too. Not saying that's what happened here but in comics he's definitely used it to figure out things that he didn't sense directly. Like having feelings of being watched when he couldn't sense anyone or finding hidden things

True, but it's also been shown that the sense can be bypassed or even overwhelmed to the point of being useless or even detrimental depending on the threat. This is most notable with the symbiotes Venom and Carnage, who last I knew did not even trigger the sense. I guess overall I just believe the picture is really reaching to add more emotional weight to a scene that really doesn't need it.

Oh it's definitely not fool prove. It's potential is nearly unlimited but it's also uncontrollable and very intuitive feel like so isn't exactly the most exact. Venom/Carnage specifically have such a well ingrained understanding of it and the ability themselves that they've adapted to counter it. Predicting around the predictions that he predicts or some ***lol. People who Peter sees as absolutely no threat like friends/family wont and well he just ignores it a lot of the time like normal people do when they get those feelings lol. You're probably right about why they put it in. They've been angling the whole mentor/father figure student/adoptive son thing since they introduced this Spidey as well as making Tony feel that weight to motivate him for awhile now and half the movie. Hell that extended scene does really. I mean these people are supposed to be completely wiped from existence in an instant instead we actually get to see them dissolve one by one slow enough they can even comment on it happening to them and leave behind ash. It's a bit heavy handed but it's also a Hollywood blockbuster so...

you're all a bunch of *** nerds
