is attack on titan (shingeki no kyojin) episode 35 filler?

Coming to Ragako, Moblit discovers that the scene is as the reports had said: rampant destruction, yet no signs of any blood or remains. Moblit is skeptical of the idea that the residents evacuated to Wall Sina while leaving their horses at the town stables.

A fellow Scout leads him to the Titan atop Conny Springer's old home while another recovers an item from the wreckage: a portrait of Conny's father and mother. He drops the portrait when the Titan suddenly stirs, and upon closer examination he is stunned to realize that the Titan atop the ruins bears exact resemblance to Conny's mother.
