Shall We Gather at the River (S02E02)

Tom is still haunted by memories of his time with the aliens and begins to wonder if they did something to his mind. Pope, who is in charge of questioning Tom, plants seeds of doubt about him among the group. Meanwhile, Ben's hatred for skitters grows, and the 2nd Mass scouts locate an old bridge that will help them cross the river to safety ahead of an impending attack. (Warner Bros. UK)
