Re: PRIVATE.
Well, he had help from other scientists but yeah, Dr. Culber - he was our ship's doctor. Gray was Adira's boyfriend, and when Gray died, Gray and Tal went into Adira. It was hard for Adira - and the Trill weren't too happy about it - but then Gray started seeing Adira as an.. apparition, something? I don't know how to describe it.
So Dr. Culber and the others decided to try something to separate Gray out - we weren't sure if it would work, but last I checked , it seemed to and Gray and Adira could actually be separated and such. It was really quite impressive. For awhile though, we didn't know if Gray would survive the procedure.
