Maybe we'll have to earn a second blade? That would be nice. I'm not a big fan of getting it immediately. Maybe they could have it so you have to kill a certain amount of guards with your hidden blade so that you can purchase the second from another assassin. That would make it more satisfying to get one, as we will have worked to get it. Or maybe it will even be part of the skill tree?
