is reaching new heights of tension on several fronts in episode 4, “We Were Supposed to Help Each Other.” Not only does the law-enforcement task force have to hunt the kidnappers, but personal tensions are rising as well.

A confrontation between Agent Susie Dunn (Rachael Taylor) and Meg Fitch (Gillian Anderson) — seen in this exclusive video clip on Zap2it — makes it clear that these sisters don’t see eye-to-eye on how best to proceed.

At the center of the argument is the proof-of-life photo the kidnappers gave Meg when she paid a ransom for her daughter, Amber. Something about that picture seems to have misled the FBI, and Susie thinks Meg knew this was a possibility. Naturally, this brings up whatever it is between the two sisters that has been festering for decades.

Considering this interaction, it’s understandable how things could go so very wrong between fiery Susie and icy Meg.

The “Crisis” episode, “We Were Supposed to Help Each Other” airs Sunday (April 6) at 10 p.m. ET/PT on NBC.
