“If You Believe in Me, I’ll Believe in You” is episode eighteen of season one of Batwoman.
Two groups are meeting at the docks, exchanging cash for body parts. The body parts are still connected to their owners; the seller says some disassembly is required. Kate appears and takes them down.
Kate and Luke enter her office in Wayne Tower. Mary is waiting, with champagne. Mary congratulates them. Kate is annoyed because the trafficker got away. Also, someone grabbed her wig and nearly pulled off her cowl. Luke makes a sarcastic, but accurate, comment about Kate’s wig. Mary suggests running an electrical charge through the cowl. She started the champagne early. Kate says they will celebrate as soon as they catch the trafficker. Mary leaves, taking the champagne with her, and Luke says the cowl shock is not the worst idea. He says Mary just wants to be a part of it. Kate says the answer is no; if Mary wants to be part of her life, she will take her to dinner. They need to focus on the journal. In the previous episode, “A Narrow Escape”, Tommy Elliot was discovered to be behind Lucius Fox’s death. He wanted Lucius’s journal – which has details on Wayne – i.e., Batman – technology in it. They need to find out where Tommy hid it.
Sophie and Julia are currently looking through a warehouse full of Tommy’s stuff – Julia has joined the Crows and Sophie has been reinstated officially. They have no luck finding the journal and contact Kate. Luke says Tommy owns at least 40 buildings in Gotham alone; who knows where he hid it? Kate says one person knows. She takes a field trip to Arkham. Tommy claims he’s Bruce’s best friend. Kate says he killed Lucius Fox, Bruce’s actual best friend. Tommy says that’s a lie; Lucius wasn’t Bruce’s best friend. He won’t say where the journal is.
Tommy is taken back to his cell and Dr Butler says he will take it from there. Alice is inside Tommy’s cell – and Dr Butler is now Mouse. Alice mentions that Tommy is going to face the electric chair. He isn’t; he was ruled unfit to stand trial. Only Butler has said he is and the Crows are going to collect him. Alice can help. She listened in on Kate. What’s the journal? A failsafe; a way to kill the Batsuit in the wrong hands. Why would Bruce’s R&D guy have that? Because Bruce Wayne is Batman. Alice did not know that. She wants the journal. In exchange, Tommy can walk out of Arkham. With a new face. To prove it, Butler reveals he is Mouse.
Luke has intercepted a call from Arkham to Johnny Sabatino’s club. In a building Tommy owns. Tommy had Johnny steal the journal from his office and hold onto it. Luke asks how they will get into a mob-infested club? Through the front door. They’re going clubbing. First, she needs something to wear. Mary helps. Mary wants to come with. Kate says it’s too dangerous. Mary reminds Kate she’s been poisoned, stabbed and nearly exsanguinated. And lived to use that as a verb. Kate will need backup. She already has it; Julia. Kate says it’s nothing personal. It probably feels it to Mary.
Kate and Julia head to the club and split up. Kate sees Regan behind the bar. Luke listens in to them chatting and reminds her about the mission. Julia runs into trouble; she’s been made. Luke thinks it’s a trap. Kate spies the journal just lying on the desk. Luke thinks that’s suspicious. Justifiably; it’s a trap.
Tommy is apparently hanging dead in his cell. He isn’t; he is kind of lacking a face though. The face is on the body, not his head. Luke contacts Mary as both Kate and Julia have been captured. He wants to go in as Mary watches the cameras. Mary asks him what he’s going in as; Sabatino’s accountant? It has to be Mary. Luke is uncertain. Mary trusts him to keep her safe. It also seems Julia is keeping secrets from the others.
