Hey, look. The current guy just made the Doctor an immortal being from whom his entire people got regeneration from. You can do anything. Just know that when you leave someone might go “yeah, that never happened”. Look what happened to the Doctor being half-human.
And by the way I agree wholeheartedly with him being a human from the future because that’s I believe Timelords are. Your starfish alien take is interesting too, though.
