'Good day to you. What are you still doing about here? Those Blackwolds are gone, and likely for good. That strange dwarf might still be around, but I'll wager he went on to somewhere a bit more interesting.
'You should take that news on to your friend Strider in Bree-town. If he sent you out here, he likely wants to know what we found! He'll probably be at The Prancing Pony. Those Rangers surely like their beer, and the Pony has the best!
'Thank you for your help, but there's no use worrying about brigands around here anymore.'
From a dying brigand at Skunkwood's old hideout, you learned that the strange Pale Dwarf was trying to bully the Blackwolds into continuing their alliance with the Witch-realm of Angmar.
You should return to Strider and tell him what you learned about the Blackwolds and the Pale Dwarf.
'You have returned just in time! Much has happened since you left, but I have little time to relate it. The tidings you have brought me will be of great use to my men here in Bree-land, but there is a more immediate threat we must deal with now.
'While you were away, those same Nazgul you saw with Amdir attacked the Pony. They were in search of the travellers I had been awaiting, four hobbits of the Shire. I cannot tell you why they had such an interest in my companions, but I can tell you that I will have need of your help again.'
