Star Trek: Every Two-Parter Ranked From WORST To BEST

13. In Purgatory's Shadow, By Inferno's Light

Doctor Bashir wasn't in prison for an infraction of the Starfleet uniform code, but he was still operating under previous dress regulations when he popped up in Jem'Hadar jail in In Purgatory's Shadow - and that wasn't even the cliffhanger! 

No need for sandwiches, there is so much plot and character development in In Purgatory's Shadow and By Inferno's Light, you'll be satiated for weeks. Full-scale war would have to wait until Call to Arms. For the moment, Cardassia had joined the Dominion, and Dukat was now head of the Cardassian 'government' (obviously!).

We learnt that Enabran Tain was Garak's father, that Breen don't have blood, and that you should only go to warp inside a solar system if that solar system is about to be reduced to cinders.
