“Weaponized” takes the top spot of the season—when an assassin unleashes a virus on the school to single out Dead Pool targets, all of the students are quarantined. The episode is tense and claustrophobic, making viewers really feel the danger of the situation. Dylan O’Brien gets another chance to shine when Stiles, terrified, stares down the barrel of a gun.
