User blog comment:ChishioKunrin/Possibly why Tyrian didn't see Qrow's punch coming/@comment-80.192.6.40-20170101213815

That's certainly an interesting theory. I would ask why he was fine with their position when they were talking but you argue he may not have had enough information to feel comfortable attacking Qrow, whereas speaking doesn't require him to know more than their vague position. I do wonder if this could explain his combat prowess to a degree too - he knew where people without having to observe them thanks to the vibrations, unlike RNJR who are limited to conventional senses (bar Ren's ability).

However, Ruby's rounds likely travel faster then the speed of sound, yet Tyrian was able to predict them arriving and block them (that said, fiction often forgets this important point). Also, wouldn't a fist displace more air than a sword because it has a larger surface area and thus experience more air resistance (given the sword was moving edge first, not via its flat side)? Maybe the effort of swinging it perhaps.

I feel that we can't just rule off it being script logic just yet - that could still explain it fairly well - but if this comes true that's some very good observation of you.
