Now, that's fine and dandy, but little sisters don't fight. I know I'm not the first, but I have an idea for the little brother.

Little brothers sometimes are seen walking with the sisters and Big Daddys. When you fight a Big Daddy, the Little Brother will use his bat and plasmids to help Daddy. They will also fend off some splicers that get to close to a little sister gathering Adam. However, their plasmids are unstable, and they won't use them to often.

Little Brothers will also sometimes engage in conversation with the Little Sister by joining in, or when she talks to him directly. They will also help her get up the vent when it's "dream time" before going in too, or when fleeing splicers, sacrificing themselves to be the victim.

They also moarn for a fallen Big Daddy, just like the little sister. They will act more hostile at that point, attacking anything that gets to close, even a Big Sister/Brother (excluding the little sister). They always calm down after the Big Brother/Sister, or the player, you, comforts them.

Little Brothers sometimes mention "...growing up to be as strong as Daddy." This is because when the Big Brother grows old enough, they turn them into Big Daddys. (Ergo, it's little brother to big brother to Big Daddy.)

If you save a Little Sister or Big Daddy from splicers while a Little Brother is with them, he will show trust towards you. The Big Daddy and Little Sister will do the same if you continue to help. And at the end, they will imprint on you, allowing you to heal them and have them come help with a special plasmid called summon. This will help at the end of the game, and will unlock a special ending if enough trust you.

Saving a Little Sister will automatically save a Little Brother as well. But trying to harvest a Little Sister will provoke him and cause him to pull the Little sister away, and you'll have to kill him before harvesting. This will almost grantee a Big Sister, Brother, or rarely both coming for you.

Any changes or suggestions? We'd all like to hear them.
