I find it almost impossible to watch both the A and B stories of Prayer. Between Aeryn's torture and unbelievable duress and then John's trip into the hell of the twisted and dying Moya reality to kill Chiana/Aeryn so that Sikozou/Stark could cross her over and they could hear the meaning of Katratzi, I'm not sure my heart could stand it.

John and Scorpius' blood oath, I felt, was over the top even for Scorpius but I'm assuming that he didn't trust John even if John was desperate enough to offer wormhole technology for help rescuing Aeryn. While Aeryn broke -- "Only Ever Crichton!" but also was able to deceive the spying alien woman, John was thankfully for his soul, unable to kill or even shoot even a twisted version of the two women he loved so dearly. It took Scorpius to do it since, in that world, Stark had to love the soul to cross it over. In the end, John learned about Katratzi, but at what price?
