My main warden is a male, who romances Leliana, so I very much picture her with a male warden.
Oh well, I suppose if I'd choosen a male warden I would have felt the same!
While I romance her with a male Warden most of the time, Leliana has always struck me as being bisexual with a clear preference for women.
She seems far more comfortable conversing with a female Warden in Origins and it shows in that conversation about hair, where the subtext has her clearly expressing her attraction to them and attempt to initiate a romance.
Compare that to the male Warden who has to be the one to (awkwardly) flirt with her to really start the romance arc between them, I think it's safe to say that while she's attracted to men as well, she tends to look to women for romantic partners or friendships.
Looking at her history, we do see a lot of the important people who have shaped her during her life have nearly always been women.
Interesting, I haven't thought about that! I mean, I noticed she's always been surrounded by women, but...Well, that's kinda cute I must say.
Ugh, I had so many ideas when I first started Origins (so before I got really attached to the characters) "do the ultimate sacriface, make Alistair rule with Anora, etc., etc." ... And now that I almost finished the game, I'm not sure about what I want anymore. Well done Bioware.
(oh and, sorry for the bad english)
