Summary:
An existential crisis was come to Finn when he deemed that he saw the face of Jesus in his grilled cheese sandwich. Ridiculous but it was truly happen. In the meantime, the rest of the optimistic kids rally around Kurt after he has a crisis of his own that leads to a larger and tougher discussion among the group about their own theology.
Rachel: Break a leg.
Finn: I love You.
