Okay, so based on the fleshed out outline for Episode 2, Olwë will now already have a family at Cuivienen, so scratch that. I feel we should in *some* way show that the elves arrive in Valinor and settle down and get married and have kids, since they are living in a peaceful, stable environment. But perhaps the birth of Fëanor idea covers that in Episode 6. [Alternatively, Míriel could visit the Vanyar home while the Ambassadors are away, and that could be the start of her friendship with Indis.]
ANYWAY, this episode needs a frame story. Haakon has suggested that it focus on the loving relationship of Celeborn and Galadriel, and perhaps we could get at how Arwen sees them as people with rather different views (certainly on the whole Valinor vs Middle Earth question) but still get along and obviously care deeply for and respect one another. That's a starting point. Someone needs to think of something that can happen to bring that out.
