Ambulance bay. Paramedics unload a little kid from the rig; he's the one shot in the neck. The kid tells Mark his name is Ted. Mark asks Ted to swallow (ew, not like that), but before he does, Ted asks, "Where's my mom?" Mark indicates the blood all over Ted and asks the paramedics, "Is all this his?" Dirk says it's not: "His mom was wrapped around him." From across the ambulance bay, Lisa calls for Mark. Dirk adds that it looks like the bullet went through Ted and into his mother. Lisa calls Mark's name again, and Mark gives Dirk some instructions before heading over to Lisa. At the rig, Lisa says she thinks the patient is Mrs. Neighbour, the woman who brought in Ben Fossen, the abused kid, last week. And...it is. Of course. Because the rest of us saw this coming from Missouri. Mark says Mrs. Neighbour's name (which is long and Polish and hard to spell, so I'm sticking with "Neighbour"), and she asks him where Ted is. Mark tells her Ted's inside, and that he'll be okay. Mrs. Neighbour begs him to take care of Ted, who apparently was bleeding quite a lot when Mrs. Neighbour last saw him. Seeming to know the answer (finally), Mark asks Mrs. Neighbour who shot her. She chokes, "Derek. I told the policeman it was Derek Fossen." The Marimba of Terror throbs on the soundtrack. "Your neighbour," Mark exposits. Mrs. Neighbour babbles, "He was looking for Ben. I told him I didn't know where he was, and he said if I was going to take his boy away from him, he was going to take mine away from me. Please! Please, help him! He was bleeding." Something attached to Mrs. Neighbour starts beeping. She starts heaving, and Mark immediately tells everyone to roll her, whereupon Mrs. Neighbour spews a prodigious quantity of blood onto the asphalt. Lisa estimates that it was about two litres. Mrs. Neighbour then loses consciousness, and they rush her inside -- and, for once, the commercials come sooner than I'd anticipated. Woohoo!
