Tonight's the Night

S2 E13: When a drunk driver knocks down a transformer, the entire neighborhood is left without power on a frigid Chicago night and members of Firehouse 51 step up to lend their much needed help. While many from the community ride out the night at the station, in the midst of such close quarters, romances speed up and tempers flare. Meanwhile, Casey (Jesse Spencer) continues to lie to both himself and Dawson (Monica Raymund) about his condition and the stakeholders in Molly's bicker about the bar's direction.
