Eddie is asked to go on an undercover operation as bait for a man attacking women walking home alone. Jamie is worried and asks her not to take the case, but she says he’s never known what it’s like to be afraid to walk home alone so he doesn’t understand why this is important to her. Jamie alludes to not trusting the lead detective but gives Eddie no specifics and the two argue over it.

After a city-wide blackout, there are complaints that a large house development was left without police presence. When Frank has Sid look into it, it turns out that the mayor called Chief Russo and told him to move more police to specific, higher-end areas. Russo thought he was saving the Police Commissioner a headache by not contacting him and going along with the Mayor’s request. Frank feels he jumped the chain of command and left poorer citizens unprotected and tells Sid to fire Russo

Sid pushes Frank to reconsider, saying that not everyone is capable of standing up to power the way Frank can and that Russo’s intent wasn’t malicious.
