If the party manages to free both Poppy and Rita, and get away before Redd comes back, Redd is told of what the party has done and now they get to deal with Redd and his band of brigands searching for them.
The party brings Rita and Poppy to the next town, village, or city. After taking care of what they need to, obtaining supplies, talking with someone that may have information about their actual quest, or selling off some excess "treasure" items. They could be spotted in the street by a couple of the brigands who raise an alert to the others and the chase is now on amongst the streets. Or they could find out that the brigands are searching for them at the local tavern when they stop to get some food or arrange lodging for the night. Perhaps the tavern proprietor has been paid to send word if the party shows up and they happen to see the proprietor talking to a kid, slip him a coin, and the kid is off out the back. Maybe they enter the local general store to get supplies and walk in on 2 or 3 of the brigands shaking down the owner for "protection money". Being out numbered, the brigands try to get away and tell Redd that the party is in town.
Now, do Redd and his brigands confront the party in town, or do they wait and deal with them along the road?
