I don't think any of it was filler, but it was a lot of board moving. Joffrey, Rhaena and her lil brothers shipped to the Vale. Cole, Gwayne and the crownland armies out in the field. Daemon taking Harrenhall. A dude claiming he is a Targaryen b*stard/half-brother of Daemon. First battle of the war between the strongest armies in the Riverlands, with both the greens and blacks setting out to add them to their side.Felt like a setup episode . Daemon and Aegon scenes were the only outstanding plot points . Rhae and Alicent meeting was okay . Everything else was mad fillerish
