A bit about the Gorn war maybe.
Edit: Nope nothing to do with the Gorn War its do to with the Klingon War.
A hard watch. We learn some more about Joseph and Nurse Chapels past and Ortegas a little bit too although it is still not clear if she was actually there or not.
What could have been do except for that ending. Could the Federation and the Klingons have become allies sooner?
I loved the design of the ship at the beginning of this episode although except for the deflector I though it looked a bit too modern more like a ship from the 24th or 25th Century's than the 23rd.
