The power went out on Chicago Fire Season 2 Episode 13. The lights went off. And the action picked up!

Crossing over its two Windy City-based dramas, NBC featured Katie getting kidnapped by the same men who were out to get Kelly on this terrific installment, with Sophia Bush coming on board and setting the stage for an exciting conclusion on Chicago PD.

Katie, of course, will need to make many important decisions now, leading with this: Will she still wish to move to New York? Might it serve as an ideal escape?

We also saw Boden get some romance on the episode, along with chemistry between Lindsay and Severide? Sort of? Kind of?
