is attack on titan (shingeki no kyojin) episode 67 filler?

Reiner Braun attacks Eren Jaeger with his Armored Titan, and though he is repelled and his jaw destroyed by the Attack Titan's hardened fist, he manages to pull away the Jaw Titan, preventing Eren from eating it. Eren emerges from his Titan's body and remarks that they are done.

Mikasa tells Eren that they should go home as Reiner attempts to stand up. She grabs Eren and they leave using her vertical maneuvering equipment.

The Scout Regiment retreat to their airship and Jean orders the soldiers grappling their way to the airship to protect if from below.
