is attack on titan (shingeki no kyojin) episode 29 filler?

Under the moonlight, two Abnormal Titans play-fight with each other as the Beast Titan ascends Wall Rose. Nanaba draws her blades alongside the head Scouts atop Utgard Castle, telling the recruits to stand aside as they put their ODM gear to good use.

As the recruits watch on, the Scouts leap into the fray. Two hours earlier, Nanaba's and Gelgar's team set up camp within Utgard as the horses rest and drink.

Henning observes that someone had been at the castle recently, and Lynne proposes the possibility of bandits.
