The second part of 9-1-1's two-part contagion arc concludes tonight with Episode 15, "Lab Rats." Several members of the 118 are still stuck in the lab from hell, and time is running out quickly. "Athena (Angela Bassett) and Buck (Oliver Stark) are in a race against time to rescue the rest of the 118 following the fire in the biolab," reads the episode's official logline. The situation births an unlikely team-up as Athena and Buck work together to save the people they love. Under normal circumstances, a team-up between Athena and Buck would be a recipe for disaster (at least for Athena), but they are of a singular mind here. A sneak peek of the episode (via Entertainment Weekly) previews this duo as they try to circumnavigate some restrictions that the army has put up, restrictions that could see Chimney's (Kenneth Choi) life sacrificed.
Nothing is worse than being made to feel hopeless, and that's not a situation Athena wants to be in. It was established that the army cannot open the lab because they would risk contagion. However, Chimney's chances of survival are worsening with every passing moment. Moira Blake (Bridget Regan) made it out with the antiviral that could save Chimney's life. In the video below, Athena devises a plan and lets Buck in. The latter thinks Athena has given up before she reveals what she plans on doing. "Even if they find Moira Blake and she's got the antiviral, there's no way they're going to give it to Chimney. He's expendable; they all are. . . . .We're going to find that crazy bitch and get our hands on the dose before anyone else in there gets sick," she says. The episode's promo does not reveal what happens, but this dose could save Chimney's life. Buck jumps into Athena's shop, and the hunt for Moira begins.
