To kill or not to kill... that is the question.
Mitchell's method of problem-solving has always been to kill, and to be fair it does often get him out of a difficult situation (Remember Graham?). However, death is a messy business and rarely does it provide the clean-cut solution he was looking for.
Nina, on the other hand, has a different approach. As a nurse and soon-to-be mother her instincts push her to defend more often than she attacks. But in the supernatural world it's very hard to be so moral, especially when dealing with the conundrum that is Herrick.
Throw into the mix Herrick's knowledge of how to survive a 'wolf-shaped bullet' attack and we have a very interesting situation indeed. We've gone behind the scenes of Herrick's return to see how the cast themselves are dealing with such a tricky situation.
For now a cease-fire is in place. Herrick survives and he stays in the house, harmless to the foursome in his current state. Yet Mitchell yearns for the secret hidden deep inside his mind, kept in a place that shouldn't be unlocked.
Something has to give. And it will.
