Desperate Housewives mistake?

In this weeks episode Betty Applewhite threatens Bree with the knowelege that she knows Andrew killed Mrs Solis.....how does Betty know this as they have only just moved in or have I missed something?!

Bree's daughter and Betty's son are now an item,and they swapped each other's dark family secrets!
