Um. I was on an away mission with my crew and I noticed something rather out of the ordinary with my Vulcan science officer. I switched armor on him as one of the Klingons he incapacitated was no longer using it.
Well...seems like Pon Farr came a little early this year. My clever little science officer however found a way to scratch that itch all by himself.
On the plus side...he's now quite popular with the rest of the crew.
