"Did I interrupt a moment or something?" he asks. "No." I snap. Rose gets up. "The Doctor is scared I can't do anything, I've tried and I just scared-" she freezes. "Rose? Rose, are you okay?" Jack asks and I stand. Her eyes roll back in her head and I catch her when she falls. Fainted? But why? "Oh my God!" I look at Jack. "Get my phone call Martha!" I yell and he obeys. We are a few blocks away from then hospital and a bit more from Martha's house.
Jack puts the phone on speaker. "Doctor? What happened?" She asks, frantic. "What happened to Rose?" She asks. "She fainted! I don't know why!" I cry, still holding Rose. "Alright, where are you?" She asks softly. "In the TARDIS. Jack can tell you the address." Jack tells her and she says that she's on her way. I lay Rose on the bed. Martha comes fairly quick.
Jack brought her in here. I'm sobbing over Rose. "Alright, calm Doctor." Martha soothes and Takes her pulse. She frowns and I look at her. "What? What's wrong?" I ask. "Her pulse is fairly-" She takes my wrist. "What are you doing?" She checks my pulse and her eyes widen. "No way." She whispers and she pulls out her stethoscope. "What?" I ask and she shushes me. She checks her heart then slowly shifts to the other side. What? "Two." Martha confirms.
Jack scowls. "Two what?" He presses and Martha looks at me straight in the eye. "Hearts." She says. "Rose Tyler has two hearts."
