I'm sorry, did I say a lot of what I wanted to say about last Friday's comic would have to wait for today? I should've said "Tuesday", but editing and a decision to make absolutely clear just what the hell is going on with a vampire Sarah suddenly appearing makes fools of us all.
(And in case it's NOT as apparent as I thought, this is basically just a representation of Sarah thinking to herself)
Fantasy Vampire (FV) Sarah is both a little taller than normal Sarah and wearing high-heeled boots. The height difference isn't as pronounced as it could be in this comic, however, as normal Sarah is mostly standing up straight while FV Sarah's bending and swaying all over the dang place.
I must admit that drawing such exagerrated poses is fun, though by the standards set forth by some in the comic book industry, she's not really defying the laws of physics or anatomy all that much.
