Piecing the magic of the Mirror out is easy now that Strange knows what to look for. After all, he was stuck in the damn thing for a few days. Strange blinks, turning off his third eye, before he looks over to Lambert. He can't help it: he looks really smug. Partly because he's a super cool magician who figured this out on his own, partly because he thinks he can one-up Childermass for an explanation.

"Remember, the Mirror was shattered. Perhaps the act of shattering the Mirror caused the magic to spread." This is all Strange spewing out hypothetical things: he'll solve the mystery of the plot with a little more prodding and a little more talking it out. "Alternatively, when all the pieces were scattered to the wind, you could have looked in it or been touched by the magic without even realizing it."
