Sylvia was secretly happy thinking that she had deceived her son and daughters by applying to join the Celestial Yin Sect with a disguise behind their backs.
In the early years, she was content to send her children to explore and grow independently as she patiently waited to see the changes in them after some interval.
But that was when the dangers were quite low that she could solve with just a flick of her finger, even from a long distance away.
However, the dangers were now more potent, with many hidden in the dark. And so, Sylvia believed she could only save them from any mishap by always staying beside her children.
It was the reasoning that Sylvia fed herself to justify her action of stalking her children.
But in truth, she just felt left out and wanted to join in the fun, especially to appreciate her darling son crossdressing as a girl and tease him while being in disguise herself.
