The search for an answer takes them to Area 51. HiboCorp has anti-Highborn weapons there, and those could give the resistance something it badly needs against the Queen's forces.
The trip also exposes the traitor inside Sela's group. She suspects Warren Cranor, Jack Frost, but it's Gideon. He stabs Britney. Warren fights alongside Sela, and Rachel helps Britney survive.
That is a nasty reversal after everything they have already been through. Sela has reasons to be wary of Warren, but those old wounds don't tell her who is betraying them now. Gideon has been close enough to do real damage before they discover what he's doing.
They get the weapons, so the mission isn't a complete loss. But now they have to carry on knowing the enemy had someone among them. The people they brought to Area 51 are not the same group they thought they were traveling with.
