let me start off by saying this is probably the second most perfect episode ive ever seen in my life i watch doctor who every once in awhile with my brother cuz he loves it, im not caught up with everything but ill watch a few episodes with him sometimes we just watched this episode and im fucking speechless this is perfecttion from start to finish it’s probably recency bias but even when that sets aside this is still easily top 5 episodes of all time the dialogue in this episode is probably the best ive heard so many amazing quotes “As you come into this world, something else is also born. You begin your life, and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower. Always coming. You will run, it will walk. You will rest, it will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep. And when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.”
