"You can't define what an 'awesome' Librarian is!" Yes, he's doing air-quotes underwater. Or would those be water-quotes now? "And even if you could, knowing Greek history and legends would be first on the list of required knowledge!"

"But would you know about the things the places are booby-trapped with? Or what artifact we're gettin'? Or how not to die because you picked up somethin' that's cursed or got a spell on it?" Of course, this is moot considering his knowledge didn't exactly help them on this mission, considering they'd both gotten themselves trapped in the ocean, but still. It's the principle.
