I know that Mary’s covering up her involvement with the British Men of Letters in this specific scene, but it does feel like her approach to hunting is different to John’s, and by extension Sam and Dean’s. She sets out to build networks and alliances with other hunters (which feels like it’s a more common approach?), whereas John burned bridges with Ellen and Bobby, two of the few other hunters he interacted with, and seems to have raised his sons with the expectation that they would hunt mostly by themselves.
