Actress Kate Dickie’s agency has confirmed that she’ll be returning in September to film scenes for Game of Thrones season 3. If Lysa Arryn is back, then Robin probably is as well, and we will get to the Eyrie at some point in s3.
SPOILER SPEC BELOW THE BREAK- spoilers for *book/season 3*
I was thinking that maybe we will see some scenes between Lysa and Littlefinger before Sansa gets to the Eyrie late in ASoS. It would be very strange to have the Red Wedding, the Purple Wedding and then Sansa traveling to the Eyrie by the end of one season. It’s possible but a tight fit, time-wise. Maybe they’ll show Lysa and LF’s wedding?
