That’s impossible. It’s impossible to sneak up from the front or back. Even if someone quickly went to close the distance he would’ve heard footsteps and prevented it; since he’s very skilled. He caught arrow midair which is much faster than a human approaching, this shows his inhumane reaction speed. So he can dodge and grab an object going 150mph while just barely regaining his balance, yet he can’t stop a human who is much slower and makes more noise. That’s already a big inconsistency right off the bat.
