Sister-in-Law
You can always have a close friendship with your brother or sister, it shows how much you Care for one another and that you'll always be close. Even though they are your brother or sister, that doesn't mean you guys cant have a close friendship. It's better to know that you'll be good friends with your brother or sister than having to hate them and always argue like most brothers and sisters.
It means that when you have a friendship, and you two are VERY close people would (or the other person) declare you his as if you were a brother, or sister to him (vice-verse [sister declare you as her brother, or sister]).

Invite both of them out, have a girls night, play a get to know you game, and if you are not the type to do it secretly, talk to your sister-in-law and tell her about how your sister feels.
Your uncles are the brothers of you mother or father, or the husbands of your parent's sisters.Your dad's sister-in-law could be the sister of his wife, your mother. In that case, her brother is also your mother's brother and is therefore your uncle.However, your dad's sister-in-law could be the wife of his brother. In that case, her brother is your dad's brother-in-law but is not related to you.
One way of looking at things:Typically it is an older brother that is jealous. It is usually because that is his little sis and he was always the one to protect her. So if the husband does anything to her it usually the brother who will support her. He is basically giving up his role of protecting her all the time. But do note that it is really not jealousy its more just a feeling love and protection. Another viewpoint:It is not true or correct to say that most brothers are jealous of their sister's husband. Some are, some are not, and no one has counted to see which group is the most. Making that assumption is uncalled for.
no he will get jealous and kill them :<
