Okay, so in Captain America: the Winter Soldier Zola is in the scene where Bucky was captured by Hydra, and considering the fact that Zola was captured on the train and so wouldn’t have been able to capture Bucky, that means that scene had to have taken place after the events of Captain America the first Avenger. And considering that Bucky would have probably died if he wasn’t captured fairly soon after falling, does that mean that Zola was freed only days to at most probably weeks after everyone thought Steve died?
My take on that moment was that Bucky was kind of hallucinating and amalgamating / blurring together different memories.
So like that might've been a memory of Zola from first being tortured in Krausberg, and/or from much later on blended with that memory (from after they've both been shipped off somewhere else in Europe, post-Valkyrie-mission, but before Zola has been officially employed by SHIELD and it's made front page news. So, eg. March - August 1945).
Because the timeline doesn't exactly make sense there, does it?
My personal headcanon is that Bucky was found by Germans (not Russians, because Russians form no part of CATFA and wouldn't have been anywhere near it). And it was they who communicated their find immediately with US Hydra (now including Zola), since they could already see that the war in Europe was as good as over.
So like... yes, maybe Bucky was expeditiously brought to the UK (where Zola was, instead of the other way around) since Zola was in allied hands, and maybe his first WS horrors at the hands of Hydra... actually went down in London or somewhere near? Maybe within the War Rooms/bunker SHIELD HQ?
Extra angst factors:
His buddies the Howlies would've been in London at the same time, drinking to Steve and him on VE-Day, with no idea Bucky was still alive and within walking distance. 😭
It's always been a headcanon of mind of half-zonked captive Bucky waking up and hearing English and American voices and thought that meant he was safe, so his earliest chances for escape, he couldn't and didn't take due to both illness and the mistaken belief he was in the hands of 'friends.'
