Is it just me, or is the Time Lord becoming way too human? What's the point of having more than one heart if you're just going to act like you only have one heart?
I just don't think the writers are seeing things from a superior being's point of view. See, a Time Lord would see us humans the same way we see hamsters. We're cute and fun and entertaining to have around. And if you lose one, you get another. You don't pine season after season over the cute little hamster that you lost somewhere. Why would you? You've got other cute little hamsters. To think we humans make that much of a lasting impression on the universe is total megalomania. Ego check: we're hamsters, not heroes.
