Communicating? Well, there's nothing very complicated to it. When the two clones on the ground cross paths, they smile and wave to one another, miming cheer and brightness. They speak with Rin's voice, but their inflections are strangely hollow.

"See anything yet?"

"Nope!"

"Aaah! I guess we gotta pretty good hiding spot, huh?"

One of the clones cups his hands to his mouth and yells up at the roof.

"HEYYYYY! Roof-chan! See anything?"

'Roof-chan' waves down and calls back, "Nothing!"

Patrol-clone nods and goes back to walking, and Prism-clone plays idly with the firewall.

Then, with a solid sounding "thuck" sound, followed by a thud, the Patrol-clone falls flat on his face, an iron-tipped arrow sticking out of his head.

Oddly enough, the clone does not shatter as if killed, but it does lie there -- bleeding a pool of mirror-silver blood.

"Ah!! Patrol-chan!!" the Roof-clone screams in that empty, emotionally mimicking way, and looks around for the source of the attack.
