Under the Crossbreeder's Knife

The last thing Christen remembers is going to get a tip for the Uber driver, then a fist to the face. When she wakes, she's in front of a woman who promises to change her life for the better... with or without her consent. She's knocked in the head again, and upon reclaiming consciousness, discovers that the mysterious Doctor Casey Borrigano's grasp of human rights and medical ethics is at best tenuous, since her cellmate has no concept of the outside world, or life as a free man.

Meanwhile, the rest of the team is going frantic with worry and has officially declared Christen a missing person. Tobin especially, is beside herself with fear and anger, and the Feds are simply not doing as well as they are purported to be capable of. They have a single suspect, present of his own free will and who is also quite adamant that they wait, since Ms. Press is assured, he claims, to be treated well and returned promptly.

As for the suspect, well... No one has given two wits about his squad so far, never mind the fact that they're just kids, and he's been at the table long enough that he knows how the game is played. The Feds find the Doctor, she kills the Feds, the kids go on suffering and the Dr.'s "guest" is altered into yet another soldier in her collection.
