070:

Balyn finds the lady sleeping with another knight. Garnysh cuts off the lady’s and this other knights head and then in a state of total despair for killing the lady he loved, he too kills himself. Balyn looks around and decides it’s probably a good idea to just leave since anyone coming along will think he killed everyone and so he just walks away, probably whistling. Balyn is welcomed at a new castle.
