Mention the tea in the microwave. Mutter something about "not swinging that way" in as awkward a way as possible.
Edna giggles, then covers her grin with a hand about five seconds after you notice it. She decides not to pursue the topic and puts a Great Value teabag in the steaming hot water.
"Well... I think it's less the game that's possesing me and more the grue itself. Listen, instead of talking about it, how about I let you see it firsthand? And then maybe you can, like, exorcise it or something. All I wanna do is play some d*** Zork!
Edna tut-tuts you and sadly shakes her head like any disappointed person in any written work ever. "Exorcism isn't as simple as just waving some holy symbols and reading out of a book, you know! That's where a lot of people get the idea that exorcisms don't work; everybody's gotten so used to doing it wrong that nobody can get it right anymore. You have to find out
why you're being possessed, and by whom, before you can do anything about it."
You hand her the disk. Edna makes a big show of inspecting it, poking it with her fingers, going over every inch of the surface with a tiny pair of dousing rods, dangling a ring above it on a string, and contemplating the patterns on the completely featureless black plastic that makes up the disk's body.
"Something's hiding inside this disk, but it's been there a while and it's hiding itself deep. It's not going to be easy to find out what this thing is, how it came to be on the disk and why it's possessing you. Do you have any clues as to who first owned this?"
