Even though Theta had sworn to stay on Earth, one thing that pulled him back to the stars was the TARDIS. She needed repairs and Theta wanted to see somewhere new. It was a win-win and gave him a genuine excuse to leave the planet.
Deciding to tempt fate, Theta allowed the TARDIS to choose their destination. After all, she knew exactly what she needed and where to find it. There he found himself at a port on a satellite for some planet in a system far away from Sol. From the constellations, Theta could tell he hadn't travelled too far. He was still within the Milky Way.
He stood by a stall, hands in his pockets as he gazed at the large gas giant the satellite orbited. Time passed by as he enjoyed the freedom of leaving Earth before a flash of red caught his eye.
Hell in high heels.
There he saw her, over by the loading bay. River Song.
Yet, he was an intruder on the universe and River was simply not his to be with. As Theta slowly backed away, his foot collided with scraps of metal discarded on the ground behind him. He turned in an attempt to steady himself but only managed to extend his arms to soften the blow of his fall as he knocked over the waste bin during his descent.
