Red Robin was already on his way to Batgirl's position, as it was clear she had found the 'path' Big K had taken. But as more and more details came to him from her he found himself moving faster and faster, so that by the time she told him that he was dead, he had to skid to a quick stop beside her as he had his own look at the body. He had hoped that Cassie might have somehow been mistaken, but there was no denying it.
The body was Big K, and he was more assuredly dead.
"Dammit."
He leaned down to examine the body, but there was not a whole lot that he could do from here.
"Cause of death is obvious enough, but the water is going to make it exceedingly difficult for me to find any clues as to our killer. If only we had-"
He paused when his communicator went off inside his cowl, listening. "Nightwing. You are the grand master of bad timing this evening. Look we just-" He paused again. Listening. He glanced at Batgirl, and then looked down at the corpse.
"You have got to be kidding me. No. I know you're not. It's just that we found Big K and... is that gunfire? Yeah, I'll send her. Right away."
He gave an exasperated sign and turned to look fully at Batgirl. "The lounge we just left is under attack by that Mask gang. Nightwing needs you on the scene, right away. I can have the car programmed to drive you back by the time you get to it."
He left out the part that either one of them could have went, simply so that they could each play to their strengths. "I'll see what else I can find here."
