So, after watching the show last night-something really didn't make sense to me. The army surrounds the group, then it waits, and keeps waiting, until it finds out the lake is re-frozen(We know post-scene that the dead can survive underwater). Then it charges with minimal forces against a small group? Was this the real reason-or was it actually waiting for something else?
