It didn't occur to Cassian not to trust Jaina's word. His gaze followed the trajectory of her hand and he saw the reptilian creature swooping down, with others in the distance. It certainly looked imposing and he didn't have the experience with the Yuuzhan Vong Jaina had described in their first meeting just the day before to doubt what she was telling him. If Jaina thought these were them, he believed her.
Without hesitation, he followed her out of the apartment they shared, running with her through the corridor and down to the street, his hand on his blaster and ready to draw it.
