The moderator says Christian has been sober fifty days now, and they're very proud of that. I'm impressed. I can't remember the last time I spent fifty hours sober. But Jack suggest that maybe a new "lady friend" helped him turn the corner.
Christian's finally had enough and says he won't let Jack talk to him that way, and Jack says he won't let Christian talk to his wife, which is awfully paternalistic of him. He looks like he's starting to walk away, as Christian yells after him to let it go. It turns out Jack was only walking away so he could get some room to charge his father, which he does, and tackles him, the both of them knocking over the twelve steps display. "Ow! My spleen!" yells Christian. At least I'm pretty sure he did.
But we don't get to watch Jack and Christian scrapping; we flash back to the island, where Jack has his eyes on the door latch. As it starts to turn, he rushes the door, surprising Juliet and knocking the plate out of her hands, which crashes to the floor, breaking. He throws her down on the table, pins her arms back, and sees her taser thing tucked into her pants, and he tosses it aside, opting instead to use a shard of shattered plate for a weapon, holding it to her throat. "Which way out?" he snarls. She pleads with him not to do this, so he drags her out into the hall, kicking at a locked door in the passageway. So he tries another door, this one with a large wheel lock and yet another Dharma logo, this one looking like a squid or something, on it. He tells her to open it. She stammers that she can't, and he doesn't believe her, despite her protests that if she opens the door they'll die.
