If there is a life changing event or a shock factor that leads to this transition, we cannot predict what is gonna happen. I just find it odd that two people who were in transition were going from C to N, if anybody knows any other reported transition, I am all ears.
I think there can be general pattern, like we have clock of socion theory, it doesnt have to go like that precisely in life, anything could happen but it is there. So I am wondering if there is some kind of an order like D->C->N->H->D, that would make sense to me in terms of transition due to supervision flow.
