To be honest I thought film production wise, I would have loved to of picked option 5 because of Lord of the rings, Two towers moment, at the end of the film where Gandalf shows up with the Rohirim and comes to save the day.  But even if everyone agreed with this, Barracker would no way be leaving his hometown under siege. So the option what a lot of yous have picked would fit in with Barracker.
