is attack on titan (shingeki no kyojin) episode 69 filler?

As Eren Jaeger looks into a mirror in his prison cell and repeatedly tells himself to fight, Hange Zoë asks him what he is fighting. When Hange changes the subject to compliment his new hair style, he demands to know why they came here.

Hange replies that it is to talk and that they never believed that Eren would sacrifice Historia Reiss. Two years ago, Eren and others of the Scout Regiment meet with Yelena and the Anti-Marleyan Volunteers at the port on Paradis Island to welcome their first outside visitor.

It is Kiyomi Azumabito from Hizuru, the lone nation on friendly terms with Paradis.
