Any time a player says "Can I..." and the answer isn't clearly in the books, you're in DN territory. Any time the rules would produce a result that feels wrong for the fiction, you're in DN territory. Any time you need to decide how the world reacts to something unexpected, you're in DN territory.
That's most of the game, by the way. The books cover the common cases. You cover everything else, which turns out to be where the magic happens.
