I didn't see this in the Vector Club gallery for Twilight, so I figured I'd upload it. The rush of uploads that accompanies a new episode makes it a bit impractical (and potentially frustrating) for vectoring; inevitably there are numerous duplicates of the favourite expressions. I've found it's better to wait a bit and let the rush peter out.
This was my favourite Twilight expression from Lesson Zero... not totally deranged, but well on her way; with a bit of creepy thrown in for good measure. This is also the first Twilight vector I've uploaded, apparently.
