Hank will also confront Walt and tell him he knows what's up and that he will catch him. Walt tells him he will turn himself in if his family is left alone.
Right before Walt is ready to turn himself over Jesse visits and tells Walt he knows he poisoned the kid. Pulls out the gun he had when Walt visited him at his house and shoots him in the head killing him. Jesse leaves and gets in his car to drive off with the girl from rehab and her kid. It ends with them driving crossing the Mexican border.
I'm thinking something similar but I think the family gets accidentally killed by the ricin.
