5. Kirsten struggles in the stitch because Linus didn’t anticipate what would happen if you used the oxytocin filter on someone of Nichol’s age. While many of the scenes are blurry, Kirsten is able to make out a few details, including an email to terminate her mother. Kirsten bounces from the stitch.

6. Fisher and Kirsten investigate Denise’s house and discover that her vault was programmed to accept Kirsten’s voiceprint. But why?
