You Are Not Alone
what you're seeing is two dots and a curved line. But you're turning it human. You're reacting to what's in front of you, and there's no harm in that, but you can't forget that you're the one doing the work. Taking a god and falling in love with him. And he's just as guilty: there's a reason they call it the arachnid reaction -- where the dots and line stay that, or turn into something worse, because you can't stand looking at something so alien as a spider or a scorpion, or a Rachnoss Empress. This is a betrayal by Earth herself, to reveal something like this at her center. To break apart the wish in front of him, after he's lost so much, and show him how horrible everything can be. How even a lonely god can have his heart broken.
Look out for the fixed points: they're anathema. The Doctor stands or dances in the heart of the storm and it turns about him. Jack is a fixed place. Rose was a fixed place, the part that kept him grounded, connected to the center. And she turned into spider babies and broke his heart. Earth full of spider babies is isomorphic to the Doctor and Rose stupidly promising they'd make it work this time: it breaks apart and bites the Doctor in the narrow ass. But Earth is also home, and he's never been good at seeing the dark side of things, so it must be the Empress that's the problem. It's not that one heart is broken, locked up on the other side of the Void; it's not that the other heart is beating twice as hard and fast. It's not that he's raging; it's just that somebody won't leave Earth alone. And luckily, he's a god. He can handle it. He can master her.
