So I'm looking for an AU of Captain America where Bucky doesn't go on the train at all. Steve didn't choose him for the mission because he had a 'bad feeling' (another Commando goes and ends up dying instead but I can't remember who). The two go on the plane together at the end to fight Red Skull. Sorry it's so vague but hopefully someone recognizes it- I thought it was on AO3, but I can't find it.
Any help would be appreciated- thanks!
