Question about 86's reaction

[Amost6x]

from this scan, I wonder if Theo should get Transonic Reaction.

I think he's just reacting to hearing the sound, not reacting at the same speed as it. I'm not sure I understand the full context though.

 

[Amost6x]

I'll summarize it as easily as possible.

He reacts to the sound of a supersonic bullet and fires a counter-**** before the bullet reaches its target.

 

[Armorchompy]

I mean it explicitly says that that can't be what's happening, given that the sound comes after the bullet
