The female lost her scent very suddenly. Not that it wasn't there, Blue could still catch it in the air, but she wasn't sustaining it now. Which was strange. She'd changed appearance too. Blue's head shifted to the other side, her tail swaying as she contemplated the threat level. Alpha wasn't giving off any stress levels, other than the indication of Rex at least, and they seemed to stand in a close proximity to suggest friend not foe.
Another pet?
So Blue held her position like told, finally able to settle into the familiar structure where her orders were clear and there was an objective revealed to her. Protect Alpha. And his pet. Whoever that was. Their directions were limited, but there would be one, and Blue would do her duty, just like before, and that would be that.
