He keeps his fingers out of the way, making sure the pages can move as needed. Maxwell had made it sound like the book itself was sentient and deciding what to do, but as he watches him manipulate the symbols in midair there does seem to be more to it than that. His sensors focus on the viscous black goop that seems to well up around the circle - but his analysis tells him nothing. In a bid to reassure himself he decides that it's because it's from a realm unlike his own and he isn't programmed with the right instrumentation to obtain any data on it. And not because it's magic.

It's not unlike watching a scientist shuffle around data trying to formulate an answer. He hadn't understood what they were doing either, but there'd been an end result like they're hoping for here.

So instead he peers down at the book as it flips pages as if in a strong breeze that keeps changing direction, trying to see if there's words or anything discernable.
