True, she was rather tsundere with Yang, we know she watched her without interacting until the train, she probably sent Qrow to save her in that flashback... but nothing of how she felt when she was with Tai.

I still think it was along along the lines of a Drunken One Night Stand. Tai could have had an unrequited crush on her much like Jaune did on Weiss, and then a few drops of alcohol in the two of them leads to Yang's conception.
