Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Enhanced Edition Leandra (Spoilers for end game)

Thanks. I replayed the battle, this time with Icara left standing at the end, and I got that option. So I guess on my first attempt Icara was more injured then I thought, and probably suffering from some status effect and she keeled over just as the battle ended.
One question though, after defeating the final boss Leandra's soul is banished by the goddess. Kinda makes all the effort of trying to reunite the sisters seem pointless. That's not a variable is it? Meaning no matter what one's choices in the game, this will always happen.
