Has anyone else noticed this about Locke?
In The Stolen Heir, it's revealed that Oak is a Love Talker aka Gancanagh (a faerie who is able to quicken desire in both faeries and mortals and also seduce them just by word of mouth) because his mother, Liriope, was also one. This means that--because Oak and Locke share the same mother--Locke was most definitely also a Love Talker. This could explain why Taryn so easily betrayed Jude, her own twin sister, for Locke. It could also be the reason Nicasia suddenly cheated on Cardan with him. It was so easy for Locke to manipulate and seduce almost everyone around him because of this power of his. It could also explain why Cardan remained friends with him even after what he did.
