Just tell your sister that it bothers you a bit that they (yep, "they". They are married now, his problem is her problem and vice versa) don't pay your mother back. Don't tell her yet about your personal feelings for your brother in law (leave that when things get really, really nasty, i.e. they are going to divorce or he treats her really bad. As long as it doesn't come to that, the best you can do is swallow your pride and don't mention that you don't like the guy.). Just let her know that if there's any problem, you will be there for her. Make sure you tell her that you love her and that she can always count on you. End the conversation with something pleasant, talk about the baby she's going to have soon.

You can also try to calm down your mother. Tell her they will probably pay her back. And if they don't, well, maybe she can just drop it (and never ever borrow them money again off course and certainly don't give him money in the near future)? It might not be the most pleasant solution, but maybe it's the best one there is to keep the peace in the family.

And a word of advice: don't borrow your children or children in law money. Give them money or don't give them anything at all, but never borrow them money.
Good Advice! Fragony, as long as your sister is happy it is very important to keep the peace.
