Author's Note: It seems like each character has their own signature expression. For Del, it's the cheesy grin, as you can see from the first panel this week. Flashfire's seems to be the raised-eyebrow "WTF?" look (o.0) -- it came out exactly right in the second panel here. Kind of a shame that it's so small.

Oh, and those are actual gas chromatograph-mass spectrometer graphs in the middle panels, just in case you were wondering. :)
