The GH-7 Medical Analysis Unit was an NPC, a medical droid on a hospital stationed on an asteroid called Polis Massa. He had a tendency to jump to conclusions about the relationship between Padme Amidala and Obi-Wan.
Revelation of the Sith Edit
As Padme was being operated on, a GH-7 Medical Analysis Unit informed the others that while Padme was dying beyond any hope of recovery, there was still a chance the hospital might be able to save...the twins.
A New Generation Edit
Darth Vader revealed that Vader had gotten certain information on the true parentage of Princess from the Polis Massa medical staff after some...persuasion. Given Vader's normal methods of...persuasion, it's at best doubtful if any of the medical staff was still alive (or in the case of the droids, still functioning) after Vader's...persuasion.
