Star Trek

Hello,

Can anyone tell me what episode of the Next Generation had an alien with a triple layered voice? It was like a male voice, coming from a female alien.. It was the scariest episode I ever saw.. Now I think I must have dreamt it.. I thought it was Devil's Due, but it is isn't? Well I don't think it is..

Thanks if anyone can help! 

hmm, the bynars?

The only TNG episodes, that I know of, where male voices were dubbed over female actors were 10010011 (the Bynars)--not very scary; and The Outcast, where the race were andrygnous but one member identified as female--she was taken away to be "cured" of her gender-illness.  The episode itself was not very scary, but it's allusion to the fad, at the time, of "curing" homosexuality can be quite distressing when placed into a real-world socio-political context.

Hope that helps,
