I was surprised, as I thought they were setting it up to be Hope. (i.e. adopted, looks somewhat like Julia Ormond, etc.) Unless Huck is really sheltered, I'm not entirely sure how the person who killed her fellow marines rather than let a bunch of innocent people be killed, is in league with the Civic Republic. I get that she may not have been aware of what they planned for the campus colony, but surely that was not their first foray into mass slaughter of innocent people.
And I did feel for Silas. I can't imagine how traumatized I would be if I killed my abusive parent, only to have him come back up as a zombie and try to kill me again.
