And now I want to know what game Grace is playing. She's on a PC, so I'm just going to go ahead and assume King's Quest VI. I recently watched a Let's Play of that which ended with singing and dancing, and it was glorious.
So yeah. That's canon now. DEAL WITH IT.
Believe it or not, this particular comic is evidence of my past self maturing. I didn't want Tedd to have the x-ray feature, and I wanted him to choose to get rid of it himself. Why was it so difficult to remove? I dunno. Probably some highly technical mumbo-jumbo that would have resulted in disabling everything else, too, short of figuring out a workaround? Maybe?
That's not definitive canon. What game Grace was playing, chosen on a whim due to a recent Let's Play viewing? CANON. The technical details of how Tedd's high-tech glasses work? I dunno. I totally have my priorities straight.
