Vala and her daughter Adria discuss the fate of two or more galaxies; their scenes precede the climax of the movie, and lead to the resolution of the Ori mytharc that spanned the final 2 seasons of Stargate SG-1.
ADRIA: The energy transferred to the Ori by their human followers used to be spread out among many. Now that I have ascended, I get it all.
VALA: If you don't kill us all first.
[....]
VALA: The Ark can only be programmed to make people believe what is true.
ADRIA: Once the Ancients have been destroyed, I will be a being of unchallengeable power, worshipped by all those beneath me. A true god by any definition, wouldn't you say?
I'd say this passes the Bechdel/Wallace Test with flying colors (literally -- Morgan Le Fay & Adria transform into pure energy and swirl around in an elemental battle)!
MITCHELL (man): We know.
CARTER: There's too many of them.
VALA: There's no other way out of here.
It isn't an actual discussion between the two women, but Carter does respond directly to Vala. One might argue, though, because Vala is talking to the entire group, so we might label it as dubious.
