In the first two episodes of Tales of the Underworld, a Force sensitive teenager named Lyco Strata discovers Asajj Ventress in a post-Order 66 timeline. He wants her help to find The Hidden Path so he can get to safety. She agrees to help after learning the group was started by her once lover, Jedi Quinlan Vos. Episode 3 is the final leg of their journey...
Let's recap everything you missed in Tales of the Underworld episode 3, "One Warrior to Another."

Tales of the Underworld episode 3, "One Warrior to Another," opens on a desert planet as Ventress and Lyco seek The Path. They come across a homestead in the middle of nowhere, and Lyco wants to at least ask for some help (they are out of water, after all).
However, a young girl in the house opens fire on them! She's no match for two Force-users, and she calls to her grandfather that there are Jedi here. The grandfather apologizes, saying they can't be too careful in the wilds. He offers them some water, despite the granddaughter protesting that they don't have much water for themselves.
The Grandfather (who doesn't have a name; they're referred to as Grandfather and Granddaughter in the credits) welcomes them. There are war medals on the wall, showing he is a veteran of the Separatists. But he's just a simple farmer now, though he recognizes Asajj by name, calling her Lady Ventress.
He says the Separatists were right about the Republic, now the Empire; Ventress quips back that they were all wrong about it all. Lyco asks how to get to Cipher Canyon, which is where they need to go. Grandfather says it's dangerous thanks to raiders, who are keeping them from getting more water to help their crops. The Granddaughter will take them to Cipher Canyon if the two Force users protect her while she fetches more water.
The trio arrives at the watering hole on a speeder with bins for water. They work quickly to fill up all the bins, but the weight of breaks the vehicle and makes the speeder hit the ground. It's a loud noise, and Granddaughter says the raiders will be coming now. Lyco works on getting it running while Ventress and Granddaughter prepare for the raiders.
Just as Lyco gets it working, dozens of raiders show up on their swoop bikes, chasing our heroes! It's a harrowing fight as the raiders want to water. But in the fight, Granddaughter clips a rock, and the speeder is down again. Raiders surround them, Ventress and Granddaughter are ready to fight, and--
Lyco stops everyone. He realizes these are the local tribe, and they're stealing their water. He lays down his weapon. The chief of the raider calls him over. He can speak their language, starting negotiations with them. He makes a deal with the tribe, but he needs Ventress, an ex-Separatist, to convince the once Separatist Grandfather.
Who is very surprised to see his Granddaughter arriving back with the tribe in tow. Grandfather says they all betrayed him. He knew he was taking the water, saying it's war! He calls the tribe "animals" since he can't speak to them. But Lyco can, since he was a Jedi.
Grandfather turns his blaster at Lyco, but Ventress lowers it. She calls Lyco her friend, to the surprise of everyone. The chief will talk to Grandfather if he is willing to listen. Grandfather lets go of his blaster, a first step in letting go of his past with the war too, and he's ready to work with the local tribe.
Later, Ventress and Lyco are traveling again in Cipher Canyon guided by one of the tribe members. They arrive at the entrance of a cave. On the other side, there is a ship where The Hidden Path is waiting for them.
Lyco heads for it, but pauses when Ventress doesn't follow. She's not coming, much to his dismay. She says this is his path, not hers. With a "May the Force be with you," Asajj Ventress leaves Lyco to head to her next adventure. But she doesn't get very far!
Because Lyco didn't get on the ship. He calls out, running after her mount. He decided he would rather be with her.
Now together, Asajj Ventress and Lyco Strata ride off into the sunset for their next adventure, which is where Tales of the Underworld episode 3, "One Warrior to Another," ends.
