Useful, indeed. Especially for a man whose specialty is raw power, not gathering intel. Maine notes the grin, wondering if Nida might be a book lover. He doesn't guess that it's due to people sharing their knowledge.

When Nida returns, Maine takes the book with a hum, careful by (very old) habit with the binding. He looks back to Nida, catching his eye before nodding.

"Thanks."

For more than just retrieving the book. Maine's grateful for the help.
