I'm pretty obsessed with New Girl and behind the scenes in depth interviews are like catnip to me so these are basically MAKING MY LIFE.

Agree with the others, killing Matt literally kills of the last of the humanity among them.

Alternate super-crazypants theory: Maybe Shane is Silas and he is looking for the grave of his dead wife and the "cure" is actually buried with her. The other crazy witch that killed her buried her so he couldn't find her or the cure to fix her.

Yes! Elijah a secret player in this chaos….although I have him maybe as part of team Shane?
