Wow, anime Claire didn't need to awaken all four limbs to beat Rigald, but she took like twice as long...
Any case, just further evidence for my swift ending hypothosis. In the manga, Claire never gained full control of her movement using only her legs; she had to awaken her arms and use all four to control her movement. With full control of her limbs at lightning speeds, I think we can expect a real end within 3 episodes, especially since Isley and Priscilla are in town and it seems that the rest of the horde isn't coming back.
