Yeah, he’s back. You didn’t really think that was the end of him, did you? Basically he’s been stranded at the end of time for an indeterminate amount of time. He’s gone completely mad, which is why I changed his face, I wanted to indicate that such a huge amount of time had passed that he’d kinda regenerated some from his skeletal form, and also that he’d gone crazy with end of timeness. He’s modified his scythe, obviously, though I’m not sure how practical it is, but it’s more of a weapon of terror at this point. Also, the “hell” Shauna2 said the ship had gone to was the End of Time we saw previously and the power drain was due to the massive black hole eating the whole universe. Which is why all the dimensions converged onto a single point. How she ended up in the main reality once they did go back, and why there’s only one Creepius at the End of Time, well that’s just a mystery for the ages.
