Jack held up his shaky hands, flinching slightly at the black flames still tracing their way across his fingers.
"Hold up there quick-draw."
On legs that threatened to give out underneath him, Jack stood up, using the nearby shelves to support himself. He looked Katharine in the eyes.
"All I know is that one moment I am jumping in for the kill - in spectacular fashion may I add - and the next I am in the wall. When I came to, Ethan was writhing and screaming, then bolted out the back door."
Jack threw his right hand out in front of him.
"And this shit is kind of freaking me out right now. There is no electricity source in that wall. I was not electrocuted. Why the hell am I covered in these...things!"

Jack breathed deeply. Losing his cool now wouldn't achieve anything. And Katharine was twitchy enough as it was. No need to egg her on. He lowered his hand, as a sign he was not aggressive.
"Now, I don't believe in any of that magic mumbo-jumbo. But something is obviously happening that I can't explain."
As he spoke, Jack found that his strength was returning slowly.
"Now, you can either help me rummage through this stuff and find out where he went and what the fuck is happening to me, or continue gawking."
In a show of what he hoped would be construed as good faith, he began to turn, showing that he did not see, or want, her to be a threat. Really though, his heart was beating in his throat.
