Apparently her phasing extends to calories not effecting her.
Well, it's kinda like with cookies. If you eat a broken cookie, it has no calories, because they all fell out.
If you're a ghost, all the calories just... fall out.

I was just commenting in chat about this and realized... It really belongs HERE! So, here's my thought.
It would be really cool if we could go into the Donut Shop in Faultline.
It could count as a Police Station, or even a whole new Day Job location.

"Yeah, give me 2 Old-Fashioneds, a Bran Muffin, 3 with Sprinkles, and a Cuppa Coffee."
Be Well!
