Booth heard a voice behind him. Instinctively he moved his weapon in the same direction. His gun was an attachment of himself, at least that was how he viewed it. It wasn't a physical attachment, but Seeley had been trained in armed combat for the better half of his life. He knew how guns worked, how they responded, everything about the inside and out of the destructive weapon. A few years before all this happened, it might have bothered him how intimate he'd become with guns. But now it was necessary. The gun locked on the figure before Booth even realized who it was. Only after he heard her voice did he lower the weapon and nod numbly.
"Hey." He stated in a lame attempt to maintain his cool and calm exterior. Seeing Kitty made him worry. She was by herself in a croat hot zone. There was a dead one on the ground at his feet. His main concern was for her safety more then her well being at that specific moment in time, but he didn't say anything until she was down behind him on the ground. Powers still freaked him out even after all the time he'd spent around her, but it wasn't just hers that wigged him. It was all powers. Even Buffy's freaky slayer strength worried him at times, but over the years he'd learned to deal with it all in his head and not give away his unease. There would always be that little voice in the back of his mind that said it wasn't possible for a man to fly in real life, or that it was insane for anyone to have the powers of a ghost. But again and again Lawrence proved him wrong. Part of him was glad for it, the other wished it wouldn't fray his nerves.
With powers came more danger, and more danger he couldn't protect the friends he'd made from. At times he felt small because there were certain limitations he had, that no one else did except a tiny handful of people. Eliot made things easier. His 'get over it' mentality honestly helped Booth keep a level head around all the super powers and vigilantes he normally would be arresting on a typical basis. it reminded him that things were different. That the people with special powers he'd come to know over the last few years would be the real difference in the world whether or not they knew it.
Seeley lowered is weapon completely when he faced Kitty more and tilted his head slightly. " Nice place." He tried for sarcastic humor and hoped she would get it. He wasn't very good at the comforting thing anymore.
