Red Dead Redemption 2 ARCHEOLOGY FOR BEGINNERS Part 141
You go to mean Rain Falls in his camp. He tells Arthur the colonel has exacted revenge by having his men assault two women. They have a conversation about death, glory, and respect; and Dutch and Eagle Flies.
When you leave the tent, Captain Monroe appears to say there isn't good news from the mayor. The three of you leave on horse back.
Captain Monroe will say he requests help from someone outside of the tribe, to not stir up more trouble. If you choose to help, your honor will go up.
The captain goes on his way, but you continue to follow Rains Fall so he can find some herbs to give you for your cough.
You'll come across a pack of wolves feasting on a horse. Don't shoot - there's no need to.
After, you'll be able to chat with Rains Fall about Dutch or Eagle Flies. But, before he can respond, you'll find some of the plants he needs.
You don't have to get off your horse. He'll pick the plant himself. English Mace. After he gets them, and returns to his horse, you'll continue your conversation.
The next time you can ask a question, you can bring up Arthur's son, Isaac.
Again, Rains Fall will put your conversation on hold to collect more herbs - Ginseng. He tells you to mix the two together to keep your strength up.
When you're done, follow him on horseback. Soon, you'll come across a teepee that has been burnt. Rains Fall exclaims the Chanupa, a ceremonial pipe, is gone.
