Jacob takes the phone call and fills Salazar in. He pulls a knife and thumbs it threateningly (because the gun he's holding wasn't threatening enough, I guess?), and Tara says he's not going to kill Jax. Salazar says he's going to make him watch him kill Tara, then he's going to kill him. Jax knocks, and Salazar lets him in, then feels him up. And, I mean, okay, dude's hot, but he's wearing a sweatshirt that says "Son" on it, which cracks me up because I find myself wondering which one of SAMCRO came up with the clever concept and then had the shirts made. It's not like they have someone hired to do just that; these people are killers and the shirt-making has to happen on the side. It just seems too weirdly out of character, though I realize it's a small thing to get hung up on in a scene that's actually pretty intense. Anyway, Salazar grabs the gun that he's stabbed into a dresser for effect, and forces Tara up with it. He starts talking about watching his girl die, and Jax runs toward him, but the gun's there. Then Jacob mans up for the first time in his life and jabs a pen into Salazar's side. This gives Jax the opportunity to hit him good and knock the gun out of his hand. Salazar flees. Jax takes a second to give Tara the gun (she's still chained up with Jacob) and tell her to kill anyone who's not a cop. Then he chases Salazar. The cops see Jax, and he lies that they're all upstairs so he can have Salazar to himself, I guess. Stahl hears the report to watch the exits and tells the cops that he's headed for the front, so she and Tyler will cover the back.
Salazar's grabbed an ax by now and Jax is still chasing him with a knife. Salazar's in a corner, and Jax tells him to put the ax down and he'll let him walk out of here alive. I don't know about anyone else, but in my world, ax beats knife. For one thing, you can hit someone from a lot farther away with it. For another, it's heavier so you should be able to get a lot more power behind it. But Salazar's apparently a pussy and Jax is a god, so I'll have to let this one slide. Jax tells Salazar he'll let him walk out of here if he rats out Hale. Cops are banging on the other side of the door, as Salazar cries, not ready to trust Jax. Then he drops the ax, and Jax jumps on him and stabs him to death. He hears the cops coming so he quickly cuts himself with the ax. Then he tells them Salazar came at him with the ax, so he had no choice. Outside, the sheriff lets Clay and the other guys know that Salazar attacked Teller with a fire ax, so Teller killed him with his own knife. The SAMCRO guys nod approvingly.
