We aren't even certain Bix cracked. The other dude who controlled the radio spilled EVERYTHING. At the end of her interrogation...the guards asked Deedra asked what to do with Bix as if she were of no help...and Deedra said they would need her later. So I am not sure Bix said anything, because one, Deedra still doesn't have anything solid on Luthen. Deedra got enough from the radio guy to keep shit moving at ISB though. And ultimately, her ambition is going to be her undoing,because she'll probably have to do something fucked up to her home planet or something of that nature.

Syril's mom is the best. And worst.
