Seth gives a half-shrug to the first question. It's not like Johnny would let him read it. From what he could tell, there was a pretty good reason for that. And also somehow connected to his power. Somehow. Seth may have experienced that power, but he sure as hell doesn't understand why it did what it did to his brain. He doesn't think he wants to understand, really.

"Yeah..." he answers with a sigh, unconsciously rubbing Daniel's shoulder with his thumb, a small comforting gesture he's not really aware he's doing, just a reaction to the tension in Daniel's body. He doesn't have any solution for that.

"And, um, he didn't write it, really, he found it and finished it. At least that's what he told me. But, um, I probably wouldn't mention it to him?" he says awkwardly, frowning to himself. "I dunno, I think it really fucked with his head, and.. I think it's connected to his power somehow? Not sure..."

Seth doesn't want to say more than that about the book or Johnny's experience surrounding it though, since Johnny didn't seem to want Seth to know about it either, and he certainly wouldn't like Seth to go around talking about it. He just wants to make sure Daniel knows not to bring it up. Being confronted with it did absolutely nothing good to Johnny's head, as far as Seth could tell.
