I probably shouldn't tell her that the air resistance equations I threw in at the end are normally only done by Physics or Engineering Seniors at college.

And I remember all-nighters with Katarina at College. Seriously, get some sleep. You'll produce a better paper that way. And Calculator's no longer working major villains - I think I've had too many of his people arrested. But Hellcat back behind bars won't be a bad thing.
