Game of Thrones Season 5 filming news

As more information on the Portstewart filming for Game of Thrones season 5 comes in each day, it would appear that a big scene will be shot tomorrow, August 7th.....

An image shared yesterday gives us reason to believe that the scene in question may be a fight scene. According to this, Ellaria finds out that Jaime has come to Dorne to rescue Myrcella, after Jaime and Bronn encounter a Dornish patrol, resulting in a skirmish.

Another source tells us that the scene being filmed this week, the “snake killing,” is in reference to Bronn killing an actual viper which he and Jaime then eat.

This picture, taken on the set, would also seem to reinforce the fight scenes.

Also, someone on Reddit leaked Jaime's entire season 5 storyline which seems to be fairly accurate from the filming news so far.

[Spoiler (click to open)]"It started with me learning that Nikolaj Coster-Waldau was going to be in Spain for most of the season. From there, I asked someone who would know. I am not going to say how I know, because that would get the person in significant trouble, and I don't want that. In fact I probably shouldn't even be doing this in the first place, but I have decided on because some people may be curious.
Jaime lifting the siege of Riverrun is out. This will not come into play at all. After Tywin's funeral, Cersei commands Jaime to leave King's Landing and travel to Dorne to collect Myrcella because she fears what may happen to her at the hands of the Martells. Jaime agrees. When he arrives he gets into an altercation with Tyene Sand. Nothing major. Essentially a show off for the audience as to who she is and her weapons. When Jaime finds Myrcella, he finds her in good health and in love with Trystane Martell. In fact I was told that is a change too. They are going all in on a Myrcella/Trystane love story, as he reciprocates the feelings. There will be a Jaime/Doran scene as well. Jaime decides Myrcella is happy and he leaves Dorne without her. When he returns to King's Landing Cersei is drunk, they get into a huge altercation, and he leaves King's Landing and sets out to find Brienne and Podrick to help them find the Stark daughters.
That's it. I know nothing about what else happens other than with Jaime".
