Bianca recently complained of harassment - there might be a lot of drivebys of their old flat by Alice. I would not want her to know the address if I was them, not to mention Alice is evil enough to give it to Bianca's ex who she seems to have contacted way back. She doesn't need to know it, in an emergency the kids would be going to Gloria anyway.well, again, I am not certain. so dont take my word for it
you can actually google it except of the street number. I just dont know if it's recent (it was recently added though) or false. So again, I'm not certain. but we are allowed to speculate
Eta if Bianca was getting mail for new wheelchairs etc, AFE would have been behind it. Who else would it be? She knew the address.
