I sort of theorise that Yang is the result of a drunken one night stand on the night of graduation. Basically Raven got too drunk and Tai was drunk as well, neither is really at fault because both were drunk, and Yang was the result. She stuck around to have the kid and tie up loose ends around Beacon, and then disappeared back to the tribe after.
