Before that can happen, time will need to move forward to the next morning. Here's why: time has been passing quite a bit quicker for Harold and co. than for Sandrina's group. Based on the distances that have been written in it really wouldn't be possible for them to get back to the estate so soon. So if someone of the good guys could wrap up the fight and move the time forward, we could get moving on that. Also, it would probably be good if Sandrina had made up her mind to search for her parents
before the bad guys shot the letter. As soon as all this takes place, the bad guys can move in.
My ideas are: Harold and co. will move in not by the road but undercover, probably leaving their horses back aways. Either Harold or Arthur (Harold wouldn't trust Sam with it...
) would shoot the note and leave quickly before the good guys can come after them. They would stick around long enough to make sure the note was read, and then ride off after Henry and Eowyn.
Sound good?
