^^^ This.

The Kubler Ross stages are really to be used more just as a very rough, broad kind of outline of what may happen, but you can go through the same stage 5 times before really coming to resolution. Everyone grieves in his or her own unique way. It is going to happen however it happens for this person and that will be completely unique to them.

Hope this helps. Don't get caught caught up in the specific stages. Just support them as best you can.
