Cayso saw the others leaving so they could make the traveling nest, and since he was left alone with Longtail, he began thinking - "A Half Flyer, half... I don't know what, in training to kill dinosaurs like me, he was almost successful... still, the others were so serene, did they know all of this may happen?...." - Cayso frowned. - "... he is too dangerous to let him live, if he didn't hesitate to try to kill me once he lost control, then nothing can stop him to attack my brother or my Herd." - Cayso really thought for a moment to attack Longtail again, but then, something changed, he saw him and as his scent changed to a scent of a normal Flyer again, the kid Fast-bitter calmed down himself, he even smiled as he thought - "I'm just been paranoid." - After that, Cayso closed his eyes and tried to sleep for a bit, until the others' return with the material to make the nest.
