Nike's eyes widened slightly at the display of brute force and also that of the Horseman's violence before her, battling that of her brother's movements which seemed to be no use. However, the throw that he gave to the Horseman did make her stare a little bit longer at the dark man himself, now knowing why it was that he was called the "Headless Horseman".
At the sound of her sister's voice, Nike turned around, only showing the mildest form of surprise. She had a feeling that her older sister would show up, and like all Zelus' schemes, or at least the majority of it, Bia seemed to be always be involved, one way or the other. Which made her all the more bitter towards her older siblings.
She shrugged at her sister's words, continuing to watch the Horseman and her brother struggle. "That man has his right to exact revenge as well. I am only lending him a hand, which will satisfy my half of the vengeance I seek upon Zelus."
