User blog comment:Schiffy/BG9: Man, Machine, or Something Else Entirely?/@comment-6904925-20130920142806/@comment-11051098-20130921002249

BG9 also said "I think only his majesty could explain" in the scene you refer to. And I doubt a machine would say "I think". However, I wouldn't call it emotion, rather a human reaction.

What about an android? Isn't that pretty much the same as a cyborg? Otherwise, I do think that BG9 is a male, regardless of being human, cyborg, android or whatever. Its appearance with broad shoulders and neck and its apparent height makes me doubt it could be female.
