Oldtimer...I agree. I think that sometimes the paperwork just isn't the thing on their mind.
Besides we read in DB and we know in our hearts that a different person, if they come back, comes back and they come back to the different person that we are.
With all the changes there must be a period of getting to know both knew players involved, right?
I would say that not filing just means they are thinking of more important things to them...they don't need the paperwork to prove that maybe?
Who knows...they are all jacked up anyway so assigning motives to ANYTHING they do is counterproductive
