Katniss realizes that the noise is actually coming from a Capitol weapon, most likely mutts. Peeta freaks out and tells Katniss to run because something is out to get her. Katniss asks the others to leave her, but they’re determined to stick by her. The group run through the tunnel and hear people being attacked. She smells roses and asks others if they can smell it, too—but it turns out she’s the only one who can do so. They arrive at a central area called the Transfer and Katniss leads them through the pods that they already know about. Messalla accidentally triggers one and dies. Peet pushes them onward and encounter a group of Peacekeepers that they were able to evade successfully, as mutts have attacked the Peacekeepers before heading towards them. With Pollux’s help, they were able to surface through the sewers. They find out that Leeg 1 and Jackson sacrificed themselves in order to let the team continue on.

Pollux, Peeta, Cressida, and a seriously injured Gale make it through. Katniss is horrified as she witnessed Finnick getting attacked by the mutts. Other members of their team are also gone. Katniss uses the Holo to destroy the area beneath them. Peeta freaks out again and Katniss kisses him hard to calm him down. Their group keeps climbing until they find themselves inside an apartment with an old woman inside. However, before the old woman could say anything, Katniss kills her.
