You play the needy table. Ok, the total is 5K. You ask to borrow $200. If they have the intention to pay you all back, they will mention you that they still owe you and they will subtract the difference.
Shady is if they will not even let you borrow the $200 when you lend them a larger amount in the past. Consider the money is gone unless you take them to court with docs to supplement your case.
It all depends on how much you value the family ties. If they shady, they are not family so I would treat them like a business transaction and will try to get the money back the legal way. It was they who threw the first stone so no guilty consciousness on your side.
Now if they needed more time, at least they acknowledge the loan and that is more tolerable.
