Well, as a friend of mine once said, "You aren't looking at the mantle while you're poking at the fire."
But I'm kidding, and I'd never want to objectify Leliana or anything.
Well, in an alternate reality where we could romance Leliana, my character would stand by her side assuming only appearance had changed. You don't just leave somebody because they look different, bad or good. Deep love is deep love, I say.
I'd never want to be one of those assholes who actually leave their wives after they have mastectomies because they don't want to be married to somebody without one or both breasts. Vile.
Just one source.
