On the latest episode of NBC drama "Chicago Fire," an arsonist was caught, while a gruesome incident caused a rift between two of the firefighters.

In "A Nuisance Call," Severide (Taylor Kinney) takes the arson problem into his own hands by trying to implicate Hadley (William Smillie) as the arsonist. He uses his "Find my Phone" app to follow Hadley to another dangerous building, where he catches him in the act. Severide's discovery finally puts an end to Hadley's serial arsons.

Meanwhile, Shay (Lauren German) and Dawson (Monica Raymund) go to take care of what they call a "nuisance caller." When they step inside, the caller takes a gun and kills himself, right in front of them. The scarring act causes a schism between them.

Benny also (Treat Williams) meets with McLeod (Michelle Forbes) to discuss Boden (Eamonn Walker).

On the upcoming episode, "A Power Move," Boden's time at Firehouse 51 may soon be up. The synopsis reads, "Boden's future with Firehouse 51 is on the line and McLeod keeps on him about his past wrongdoings in Chicago Fire Season 2 Episode 5 "A Power Move" airing next Tuesday on NBC."

The promo shows Severide saying to Boden, "This is your house. Defend it!" The promo also teases that Shay may get a love interest in the future. 

TVLine also reports that after the suicide Shay and Dawson witnessed, the mixture of guilt and blame that both feel will keep driving Shay and Dawson apart-- so much so that one may consider leaving Firehouse 51.

"A Power Move" airs Tuesday, October 22 at 10 p.m. on NBC. Check out the promo for the episode below.
