She is Jackson's sister and has run off with the neighbour. He has been a bachelor for a long time and finally gets to raise chicks. Bequette and her mate did not overlap during their moult. She moulted with her new mate and when her old mate finally arrived to moult he was very sick and had to spend most of his moult in rehab. He survived and is busy incubating a dummy egg. This will prevent him from egg-envy and trying to take over the nest and the eggs of his old mate.
