libertybell all i want for christmas is a half sibling! details under the cut!
Basically they would share the same father. Their dad used to be in a band and their moms were both groupies, even rival groupies, who both slept with him and got pregnant. The dad was an Englishman and still lives overseas. He was very distant and really has no relationship with his kids, but a month or so ago Lyndi got a letter from him asking her to come visit him for the holidays. I'm sure he would've sent one to your kid too and Lyndi was all torn, etc, etc. Also I thought it would be fun if they grew up together because their moms set aside their differences and managed to raise them as a family unit, but that doesn't have to be set in stone.
