I hope Data doesn't return to the fleet full time, as it would seem to limit him in his new role as all around awesome Android explorer
Yes and no...
With Data 'out there' exploring the books could quickly come down with a case of 'Worf Syndrome'. Trying to figure out ways to incorporate Data into stories even when he has no business being there.
Data will need to eventually return to the Enterprise
, perhaps as some type of civilian advisor?
