After last week's episode of Game of Thrones, the preview for Sunday night's Book of the Stranger gave us our first look at Petyr "Littlefinger" Baelish (Aidan Gillen), who has been mysteriously absent through the first three episodes of Season 6. Of course, the show had more important matters to delve into, such as the resurrection of Jon Snow (Kit Harington). For those who need their Littlefinger fix, rest easy, because today we have new photos from Book of the Stranger featuring a closer look at Littlefinger and more characters from Westeros, including a sibling reunion.

In HBO's preview for Book of the Shadow, Littlefinger is seen telling Robin Arryn (Lino Facioli) and Lord Yohn Royce (Rupert Vansittart) in The Vale that Sansa has escaped from Winterfell and that she is in danger. Last season, it was Littlefinger who helped set up the arranged marriage with the treacherous Ramsay Bolton (Iwan Rheon), before returning to King's Landing. We learned late in Season 5 that he had formed an alliance with Olenna Tyrell (Diana Rigg), who needs Littlefinger's help to get her grandchildren Margaery (Natalie Dormer) and Loras (Finn Jones) out of jail. While we'll have to wait and see what happens with that story, it's clear that Littlefinger has returned to The Vale, but we'll have to see where he goes next.

We also see a new image of Olenna Tyrell, who may be starting a new alliance with Cersei Lannister (Lena Headey). In the Book of the Shadow preview, Olenna agrees with Cersei that Queen Margaery Tyrell (Natalie Dormer) must not repent her sins in the city, much like Cersei did last season. What's interesting is Cersei most likely has no idea that Olenna and Littlefinger helped orchestrate the death of Cersei's evil son, King Joffrey (Jack Gleeson), but we'll have to wait and see if Cersei finds out the truth this season.

In the second Season 6 episode, Home, Sansa Stark (Sophie Turner) and Theon Greyjoy (Alfie Allen) were saved by Brienne of Tarth (Gwendoline Christie) and Podrick (Daniel Portman), after being cornered by Ramsay Bolton's men. Brienne offered her protective services to Sansa once again, but this time she accepted, as Theon revealed he was going home, to the Iron Islands. We saw in the preview that Theon will reunite with his sister Yara, although Yara isn't too pleased with Theon. We see a new glimpse at this reunion in one of these new photos from Book of the Stranger below.

These photos also give us a new look at Tyrion Lannister (Peter Dinklage), who, according to this episode's brief synopsis, "strikes a deal," along with Jorah Mormont (Iain Glen), Daario Naharis (Michiel Huisman) and Daenerys Targaryen (Emilia Clarke). Sunday night's preview teased that Jorah and Daario had tracked Dany to the Dothraki capitol Vaes Dothrak, where she must live out the rest of her days with the widows of other khals. We'll have to wait and see if Jorah and Daario have what it takes to set Dany free, but until then, check out these photos below.
