I'm not sure where this would go, because of the interesting way this ep was structured: it's not intro caps but more of a "season preview" as alltsa
mentioned, so I'll try here.
The first picture looks like Cat/Jessie and that's definitely Dubrovnik.
The next two pictures are from Cascais, near Lisbon. In the first pic you can see Seixas palace in the background, and the second is on Rue Frederico Arouca (source
The winter pics (dogsledding/cannibal hot tub) are the most interesting. On one helmet you can see the outline of кострома/Kostroma oblast and a dogsled logo. There is an international race
(albeit out in the boonies) with an Aussie connection (video
). Maybe the race goes there, or maybe production had them brought up from Kotkishevo to St. Pete. Or maybe the helmets were just made there
--take your pick.
