Okay, ordinarily, I'd let it stand there; in fact, I don't even care about whether or not I win this; I will officially concede defeat. However, there are several things you said here that could have been better thought out:
1) You're right, I never said she'd taken it over; I just said she could.
2) No-one's in space; Granny and the arena have just been crushed by gravity.
3) I figured you'd know this, but I guess you haven't read enough of the Discword series to; Granny's mind can exist independently of her body; In fact, when she was killed by vamipires in Carpe Jugulum, she was able to circumvent death in this manner.
PS: I'd reccomend locking this topic in the near future.
"I meant," said Iplsore bitterly, "what is there in this world that makes living worthwhile?"
Death thought about it.
"CATS," he said eventually, "CATS ARE NICE."
