So this is just a little headcannon I've had since my recent rewatch of Stargate: Atlantis. Teyla's world changed the moment she became a mother. Ronon asked her once if she was going to try to protect every version of her son in every universe. She unequivocally knew the answer to that question was yes. What Ronon didn't understand was that a mother's love crossed space, time, and universes. A mother's love was unending.
