Even if you don't bother to play through ED, even if you create a character for FoV, you still get the Dragon Stone, even if you don't bother with the random guys on the platforms and use the services of the people in the city, you still get your Hermafroditus in any case. And it's far easier, far more comfortable when you find out they need a woman to play the role of Camilla, you can simply teleport to the tower, run across the room, jump down the lift (or take the lift down, mine is always down, it's quicker to jump really) and speak to Herma, than going through 4 loading screens in total to visit Chez and back to the Playhouse. Chez still has her use as an alchemist, but her barber services aren't really needed, if there is a much quicker way.
I don't really think those two are the same girls, eventhough they didn't give you any quest, that would announce them as "Because of Damian's attack, everyone in the Broken Valley Village is dead. That includes So & So*" (*insert the names of the two gossip girls). I think the attack came all of a sudden, there was really no time to evacuate most of the people, considering no one saved the most important one - Richard of Aleroth. He would board the Zeppelin among the first people, but the questlog lists him as dead. Reminds me, when you later meet his daughter, there's almost no interaction regarding her father, mentioning that your character met him, worked for him or anything like that. Would make a better connection between ED and FoV.
