The lie detector can create a lot of tension. If it shows that a character is lying, others might start to distrust them. For example, if a team member is wrongly shown as lying about their whereabouts during a mission, their teammates could become suspicious. This could lead to a rift in their relationship until the truth is uncovered.
One interesting plot twist could be that the lie detector is actually malfunctioning but gives correct results in a completely random and unexpected way. For example, it might say someone is lying when they're actually telling the truth about a minor detail, but that minor detail leads to a major discovery. Another twist could be that the person operating the lie detector has an ulterior motive and is manipulating the results to frame someone. They could be using it as a tool to further their own secret agenda within S.H.I.E.L.D.

The agents would then have to protect her while also trying to figure out how to use her abilities to their advantage.
