It didn't take me and my first Lavellan to realize just how much of an outsider they were in terms of not being fully connected to the others. After all, everyone is pretty much an Adrastian who don't really think that much of how the Chantry has harmed not just mages, but elves as well. Only person who understood that was Leliana, while Cassandra believed that the reason for Lavellan's hatred was because she was an outsider, not that she had a huge list of grievances. Lavellan can't really relate to anyone outside of Solas. Perhaps in a few instances depending on how you headcannon you're Lavellan's background, such as mine relating to Josie's desire and determination to help her family. But beyond that, Lavellan doesn't really have anyone.
Sera is to absorbed in her "I hate all things elfy and Dalish, including people who exhibit those traits," to be any sort of friend, but instead a loud, toxic reminder of her outsider status. Cassandra is to warped up in her own failing faith to be any comfort. In fact because of this she does more harm, wanting the Quizz to be the Herald and dissing elven beliefs, such as her comments at the Temple of Mythal, and she is a bit racist at that. (When they're making you Inquisitor, ask her in disbelief that they are making an elf the quizz.) The Iron Lady, I wouldn't even try. Josie is a bit better, but when my Quizz told her how humans have threaten her family's lives she was astonished. Josie means well but she can't understand her. As for the rest, not much comfort either, but not as isolating as everyone else. So really, the only person she doesn't feel like an outsider to is Solas. Solas is the only elfy elf there and only one who doesn't see her as the Herald or the Quizz.
So I don't see mine getting over Solas either, especially since my Lavellan saw him as a refuge she could go to when she was tried of the stupid shems and the responsibilities. Responsibilities that were never expect from her before, until a giant hole rips open in the sky.
As for Cullen, my Quizz started to warm up to him after he told off Chancellor Roderick and that he and the other Chantry folk would just hang her without a trial. She respects him, but she can't see herself with a human. For a few reasons, 1) she is afraid of being exiled from her clan, and 2) her dad always told her that it was impossible for a human to really love an elf. They just see elves as pets and nothing more.
It's interesting how we can all have different game experiences and roleplaying potential because of all the layers and options the writers put in.
Solas was no elfy port in a storm for my Inquisitor by virtue of being an elf - they both had pointed ears and there the similarities ended. To her he's just another flat-ear and therefore no different to the shemlen. He often asserts that her people aren't his people, and sometimes put the Dalish down, spoke of them derisively or made a jab about them (of course I understand WHY, I'm just talking about RP lol). She kept having to defend them and their culture and he kept telling her they had loads of stuff wrong. Also, Dalish live in tightly-knit clans where the loss of even one or two young hunters impacts the group greatly - they believe they're each a tree in a forest, a part of a greater whole - a craftsman can easily give his father's special bow to a young hunter because 'his hand is as my hand'. When you come from such a culture, a solitary man who lives on his own is incredibly suspect. His lifestyle is odd and alien, and he seems to have nobody's back other than his own. [RP perspective again for emphasis, in case anyone thinks I'm bashing him or something]
My Dalish spent the game defending Dalish elves on all sides - on one side from Sera and Andrastians, and on the other side from Solas and figures like Abelas.
By the time my Dalishquiz began to see City Elves and other non-Dalish elves as elves - to see all modern elves as her people - Solas comes out and admits he sees NONE of them as even people, never mind sees them as his people.
