'Boss' Season 2 Finale Preview Clip: Mayor Kane And Alderman Ross At Odds Again (VIDEO)

Mayor Tom Kane, played by Kelsey Grammer, has been solidifying his hold on Chicago throughout the second season of Starz' "Boss." In the penultimate episode, he pulled off a last-minute move that saved the city from falling into the hands of an interim city manager. The city was in terrible debt and about to default on its loans with no solution in sight when Kane pulled out his biggest trick yet.

Earlier in the season, he'd convinced the residents of a low-income community, Lennox Gardens, to vacate their homes with the promise that the new development built there would welcome them back. This project proved a sacrificial lamb to Kane's ambitions and the city's needs. Instead, he unveiled an ambitious plan to build a massive hotel and casino on the site, promising millions in revenue. And off the promise of this structure, the city was able to secure loans to handle its immediate financial crisis.

With the threat of an outsider taking over the city, Kane and Alderman Ross (James Vincent Meredith), his political foe for many years, even managed to put aside their differences and work together. But, as seen in HuffPost TV's exclusive clip above, such truces are temporary at best. Ross may have helped Kane secure his casino plan, but it's not being built in Ross' ward, so he wants some concessions from the mayor to ensure his community benefits from this project as well.

There's always an ace up Kane's sleeve -- especially since his experimental treatment seems to have largely suppressed his mental degradation -- so anything could happen in the Season 2 finale of "Boss," airing Friday at 9 p.m. ET on Starz.
