Yes, yes, and yes.

For those who don't know who Marina Campbell is aka Mr_Ginger_Jasper...here's a summary.

She worked as Ron Moore's assistant from the beginning of Outlander. She's Scottish, lived in Glasgow, originally from Isle of Lewis. She was Ron's assistant and that's how Sam and everyone else on Outlander met her. Then she did other things for Outlander--writing assistant or production assistant I think. She and Sam would work out at the gym with Valbo, they all became friends. She lived close to where Sam lived in Glasgow, so they would hang outside of the gym as well. She's actually the one Sam went to Paris with for a weekend in late 2013, NOT Cait like Extreme Shippers would have you believe. The Sam and Cait in Paris 2013 FALSE story was debunked by me and others. Marina's ubiquitous fur hat gave her away. There were some rumors Sam and Marina may have dated, but nothing was ever substantiated. Marina moved to L.A. a few years ago, also became friends with Amy Shiels, Sam's other long time pal, and also rumored hook up. Marinas dog, Jasper was like the Outlander mascot, he died a few years ago. Marina got married to Alan Vespe. They live in L.A. (Long Beach, which is a beach town south of Los Angeles) so Sam probably visits whenever he's in town and has time.
