The issue is that Marla should never have looked at the clean-shaven, wax-chested, turban-less Khan in his cryopod and thought he was "probably a Sikh". It's like she earned her posting on the Enterprise be collecting enough cereal box tokens.
Khan was an Indian Sikh as imagined by writers with no clue what they were talking about.
Oh, I agree. I'm not sure why the writers made him a Sikh in the first place. And yeah, McGivers too. I mean, if she recognized him as Khan from the get go and knew his 'history', that'd be one thing, but there was no indication she recognized him at that point.
I was just trying to be funny
