Everybody knows that Tommy Gavin is a little crazy, but too crazy to run into burning buildings? Find out tonight, when he has his FDNY Section 8 review. Meanwhile, Mike goes through with his plan to buy a bar, and a French writer (an attractive young woman, not surprisingly) is wandering around the firehouse, asking the guys to talk to her about 9/11. She gets an earful from Franco, who calls the attacks "an inside job" - a view echoing that of Daniel Sunjata, who plays Franco.

Plus, there's still the little matter of an elimination to get to. One consistent this season has been the variety of contestants popping up in the bottom two. Will that hold true tonight as well?
