Chase makes an appearance to show Roz her MRI, which shows that she's bleeding internally but doesn't show the source, making it totally useless. Chase wants to do exploratory surgery, but he has to admit that even if they do find and fix the leak, it won't cure Roz's mystery disease. Just possibly keep her alive long enough for House to. Roz refuses to have the surgery until after the sun sets. She figures she'll probably die on the table anyway, so she'd like to have one Shabbat with her husband before she does. Yonatan begs Roz to have the surgery as soon as possible, but she won't budge. So much for obeying your husband.
So Chase goes to the meeting room to tell House and company that the patient won't consent to surgery for another eight hours. "Nice work, Chase," House says. Chase asks if he can go now, seeing as he's now been in two scenes in one show, which is just crazy. "We need you," House tells him. Whaaaa? It really is opposite day! House continues to tell Chase off for not getting Roz to consent to the surgery, which was the only reason why he said he needed Chase to stay in the room after all. So, Chase leaves. Taub disagrees with House's assessment that Roz is suicidal, saying she just wants to make sure she has one meaningful experience with her new husband before she dies. Kumar makes fun of Taub's newfound faith, but Taub persists, saying Roz is trying to connect with all of the years she won't have. House points out that if she just let them do the surgery now, she'd get to have those years. With that, Chase pokes his head in the room with an idea of how to get Roz into surgery now rather than later. He even appeals to House's messiah complex by calling him God. See, new Cottages? That's how it's done.
Chase's idea (for which he will not be participating, of course) is to pull a Mission: Impossible and make Roz think the sun has set by sticking black paper on the windows she passes on her way to her Shabbat. Roz thinks it's too early, but Taub just lies that she's too doped up to tell time. They get to Roz's room with the Shabbat dinner and Taub tells her to pray and scarf down some challah so they can get to the cutting. I thought you weren't supposed to eat before surgery. I guess they'll make an exception for Roz the Super-Difficult.
