Betty has the Big C and is going to die...

Also, does anyone else find it ironic that she is dying from lung cancer caused by cigarettes, the very thing she shared with her daughter episodes back and what she lived off of. (Not only did she smoke everyday, but also, Don made a great deal of his money, while they were married, from working with Lucky Strike. So, the thing that’s killing her actually put food on their table and supported their lavish lifestyle.)
