DW question because I forget

The space lesbians (splesbians?) from "The Impossible Planet" I think it was, Ida and Scootie or whoever they were, they weren't really lesbians, right? As in, they totally could have been lesbians, but we don't know, it was subtext rather than text, right? Because I totally remember them as lesbians, but I think that's just because my flist told me so so many times I began to believe it.

I really don't remember.
