To address Odola's concerning re: geography
In the last episode, the confrontation with the Sons of Fëanor led to Celegorm and Curufin fleeing and taking the road through Nan Dungortheb east. Their confrontation with Beren and Lúthien takes place to the west of the Brithiach crossing of Sirion, not far from Tol Sirion. The Fëanoreans had been heading north; now they've turned eastward.
Beren and Lúthien thus begin this episode at the place where that confrontation took place. They will stay there until Beren is well enough to move. Then, they will move again. They may be wandering more or less at haphazard for part of this story, but they are aware they are being hunted, so they do take care to conceal their location and movements.
Eventually, they turn east as well, heading in the direction of Doriath. They don't make it very far when Beren slips away. After Lúthien hears the sound of a confrontation and investigates, she comes across a skirmish between elves and orcs and at this point decides to seek out Beren. The ill-fated elves Lúthien witnesses the demise of set out from Tol Sirion towards the beginning of the episode, and they do find the site where the Leap of Beren happened. Daeron parts ways with them and winds up in the Dry River.
And so, our action for this episode takes place within the highlighted yellow space on the map
