Have to agree with Shadow here - we know Yang has been searching for her mother, Branwen looked very similar to Yang in the dream sequence (doesn't prove anything per se and I know Shadow argued it was wish fulfilment, which I'm ambivalent about but still) and Yang woke up as Branwen was leaving - typically signatory of a relation between the characters in fiction, unless RT is going somewhere else with this but I can't see why since it's essentially a curve ball with no precedent to build on - we have no evidence of a twin sister, ergo mother, whom we know she is searching for makes sense. So unless Branwen is in fact a Penny level robot or something equally ridiculous, I'm going with the mother.

Sure none of the theories are correct until confirmation but the balance of probabilities, it's probably her mother.
