I guess Sam is now in California with Pharos and Pieter. Because this weekend and almost next whole week they have activities in mountains and Pieter had tagged Sam before for next weeks activities. Then, like few minutes ago Sam liked idyllwildpictures. One of them who are now "at the top", in movie by the company is emrhyscooper, and he is now in Pharos Mountain Lodge. So guess that Sam is there. And this night (like 02:15 UK time, he posted on Twitter).
I don't know if it actually means anything, Anon. I guess it's possible. But Sam is supportive because Donal Brophy, one of Cait's long time Irish besties is part of Idyllwildpictures. Sam has been friendly with him since Outlander started. There he is in the back of this video 👇
Donal is Irish, used to live in New York for years, owned a restaurant/bar called Highlands. And that's where the Outlander Season 1 premiere after party took place in July 2014. 👇
You can see Donal also tagged Amy Shiels, who is also Irish. And was Sam's DATE for the premiere. I've posted all the insider source details from that many times.
IOW, Sam has a connection to Idyllwildpictures stuff outside of Pharos and Pieter. BUT, you could be right and he could be gearing up to be there. We shall see...
