Dean Redding Before the series started they worked together to arrest Deans father Daniel Redding. Dean branded Agent Sterling to try to convince his father.

Cassie In Killer instinct they have a hard time getting along because Cassie believes that Veronica wanted to shut down the Naturals program. In order to prevent Cassie from sneaking out, she puts an ankle bracelet (tracker) around Cassie's leg. In the end, both of them are kidnapped by the Unsub.

Cassie goes willingly because she believes the ankle bracelet will set off an alarm so the other Naturals can find them. Only to find out it was fake. Agent Sterling tells Cassie to run and for the Unsub to take her instead.

She worries about Cassie because Cassie often worries & takes the cases personally. Cassie has a hard time distancing herself from them, unlike the other Naturals.

Laurel is also Agent Sterling's half sister (both have the same father).
