Burning Ice, Hidden Fire - Episode 7

An uninvited person bursts into an apartment and is ordered out but stops to point at a huge cockroach. The resident, unfamiliar with such pests, complains the floor is dirty and asks for slippers. Someone kills the bug with a slipper, then realizes the shoe landed on another person's foot — "You put that bug-killing slipper on my foot?" — and demands new slippers. Suddenly the lights cut out; one insists they're blind and tells the other to take responsibility, while the other says they don't know what a power outage is. They end arguing in the dark, blame unresolved.
