Idk abt being behind but the way the scan describes it has nothing to do with his reactions capabilities, it could be either
1. Being out of his field of view
2. He simply wasn’t paying attention to the bullet
You clearly have not read the chapter we are referencing, and that is a bad look when you’re trying to dynamically upgrade a verse off a single feat. The Titan’s Curse chapter 12 is where he doesn’t see the bullet but blocks it.
“They stepped from the trees on either side of the road. Instead of gray camouflage, they were now wearing blue New Mexico State Police uniforms...They drew their handguns. The first skeleton fired. Time slowed down. I won't say I could see the bullet, but I could feel its path, the same way I felt water currents in the ocean. I deflected it off the edge of my blade and kept charging.”
He was staring dead at the skeleton, charging at it even, when it shot a gun at him. He then admits he didn’t see the bullet but felt it’s path, so he managed to block it.
You’re crying for scans but don’t provide any yourself.
The only other bullet dodging feat in this scuffle with skeletons is when he tries to pull up his cloak to protect himself after they fire, but is helped by the angels instead. If he could perceive bullets, and was thousands of times faster than them, he would be easily blocking all the attacks from these skeletons and seeing them in slow motion, not needing to tell a bullet’s path.
I’m not even calling for a downgrade here because the cast has feats higher than this bullet feat, but you’re attempting to claim they’re massively above everything else we’ve seen in the series with a terrible misinterpretation of a simple look away from something suddenly burning bright.
