So, new theories: Jink is the child of Yun and Cutter. Also, the Cutter-freak out face Wendy teased us with is his reaction to being hooked up to the Elfin Psychic Grapevine. The last time we saw him look that freaked out was when Skywise and Timmain blanked the Palace under him and he couldn't handle the vertigo. This may be something similar; maybe he can't take having so many others' thoughts so close to his own. Leetah didn't look so upset because, as she's never had a soul name, this is similar to how she's always experienced living among the Wolfriders, just different in scale.
