Initial meeting might be a bit tense as Seda has that deep seated resentment towards the Dalish still going. (the girl really holds a grudge) Still she does secretly (deep deep down) miss the forest and the ways things used to be and will probably gravitate towards other Dalish elves though she will be very aloof at first and a little standoff-ish.
Of course once she finds out about the whole exile thing she will be very 'bah clan, bah forest who needs them. you guys are much better off out here'. After this discovery you might also notice certain (not so) subtle protective tendencies even if you are older than her.
