I like the little bits at the end, seeing old dead characters again in a new way is nice.

It's possible that when his phantoms dispersed, he at least tried to keep an eye and an ear open in order to not lose sight of Kaname.

The smokescreen could still block his vision, and the flashbang probably numbed his senses so he'd have trouble keeping track even if he summoned new eyes.

Just a guess.

I was wondering the same thing. It may be that he has some degree of passive awareness of a targeted area, if only during and for a short period after his clones are there.

So I just realized a loophole in the plot of this specific chapter. When Ouji told Kaname that he'd spotted Kanehiro's real body, Kanehiro's Halation Ghosts were already dispersed, and Kanehiro himself wasn't using Binoculars nor had scouts to overhear, so how did Kanehiro know that Kaname found out where he was? Keep in mind that Kanehiro's real body is MANY miles away. It's not physically possible for a person to see or hear any significant details from that distance.
