Datak freaking out, a weird brooch, a nuke and 2046 pantsuits! Get the story behind "Down in the Ground Where The Dead Men Go."
Nolan and Irisa come upon a cadre of Castithans gathered around Elah Bandik, the dude that ditched the fight with the Volge last episode. His cowardice is a disgrace to the Castithan race punishable by death, which is exactly what's happening to him - the crowd is putting rocks into a pulley that's stretching him to death.
Nolan tries to put a stop to Elah's torture, causing conflicts with Datak. Amanda (working a chic scarf cast) shuts Nolan down, reminding him that Castithans are allowed to practice their own cultural traditions as long as no other races are hurt.
Meanwhile, Amanda's ex-assistant Ben (we're assuming she fired him, given he tried to kill the town) is seemingly revived from the dead by the mysterious Mr. Birch. Birch, one of the masterminds behind the Volge attack, gives Ben new orders on how to clear the town (casualties be damned).
Over at the McCawley home, we learn that the alien apocalypse didn't stop people from having great kitchens. Also, Christie and Rafe fight about her engagement to Alak and Quentin gets word about an explosion at the family mines.
Quentin, Rafe, Nolan, Amanda and Irisa huddle together and realize that Ben was behind the explosion, that he's got more explosives with him AND that he's fled to Old St. Louis, which is now buried underground thanks to alien terraforming, but largely intact.
Before going down the rabbit hole, Nolan warns Irisa to not get involved with ceremony involving Elah Bandik. Irisa is very cleary upset by the whole thing.....wethinks there's something deeply personal about this. But what?
Meanwhile, Stahma (who sometimes wears clothes) tells Datak that the slow torture of Elah may be a Castithan tradition, but it's offputting to humans - and they made need to adapt (unspoken, to become more powerful in town, they have to play nice).
Alak comes in and tells his parents that Christie's shaky on the engagement because of Rafe. Stahma assures her son she'll make everything better and gives him a creepy hug, only made creepier by the fact that she's basically naked.
Amanda speaks with her mentor and predecessor, Nicky, about the Elah Bandik situation. She's clearly torn - keep the tenous peace amongst the races or do what's morally right?
Meanwhile, Nicky - the mastermind behind the Volge attack and of Ben's mysterious new orders - is committed to her plans to clear Defiance by any means neccessary, but emotionally affected at saying goodbye to Amanda. Also, thank heavens pantsuits are still around in 2046.
Down in Old St. Louis, Rafe and Nolan bond over their shared memories of the town. Nolan (and we) learn that Rafe's family used to run a dog food empire! They also figure out that Ben is planning on blowing up the old nuclear power plant, which will kill everyone in town.
Rafe shoots Ben before he can get nuke-tastic, and is tempted to murder the Indogene for killing his son (doesn't help that Ben taunts Rafe about Luke's death). Nolan wants Ben alive to find out why he wants Defiance obliterated. Ben grabs the gun and shoots himself rather than talk, only saying "Tell Amanda I'm sorry" before falling to his death.
Back in town, Irisa can't take Elah's slow torture and cuts him free - threatening anyone who gets in her way. She gets a little help from deputy lawkeeper Tommy (who seems to fancy Irisa, don't you think?)
Stahma visits Christie, who admits her father is pressuring her to end things with Alak. Stahma encourages her to follow her own heart, relating a totally twisted story of how she was betrothed to another by her parents, but ended up getting with Datak because that's where her true heart was. Oh, also her first fiance got blown out of an airlock, probably by Datak. Happy engagement!
Datak and his goons attempt to take Elah back from Irisa (who's packing serious heat), but Amanda steps in and says that Irisa and Tommy are acting on her orders and she's pardoing Elah Bandik. Datak's back starts to go up, but remembering Stahma's words about making nice with humans, acquiesces (through gritted teeth).
Datak's got another trick up his sleeve. Later, he takes Elah off to be executed, having convinced him that it's the honorable thing to do. (P.S. Like the cover of "Come As You Are" that played over the ending montage? It's by a band called Civil Twilight - available here).
Rafe, depressed over Luke's death, visits his son's room and finds this really bizarre artifact that seems alien in origin and also maybe is a brooch that Carrie Bradshaw used to wear?
