Tabitha's arrival in Beijing had awoken the local Horde King, one who was not necessarily aware of her current fractured mental state. And it was perhaps because of this he approached the woman with little regards to caution.
Her tale of misery was, after all, not exactly common knowledge, and only those who had been close to her prior to her insanity knew of her folly and the results it brought upon her. Such as Lilith, and of course by extension Gwen who was close to Lilith.
Tabitha had deliberately kept the Horde King in charge of Beijing at an arm's length. He was a man deeply infatuated with her, but it was an unrequited love. And now that he had entered his domain without daring to reveal herself, it was a level of disrespect that he would make her pay by offering herself up to him.
