• Soulmate marks trigger with a combination of eye contact and direct skin-to-skin contact and are usually traceable to an event that is either directly responsible for the soulmates’ meeting or will be exceptionally significant in their relationship. 
• Steve and Bucky got theirs in before they ever spoke a word to each other, when Bucky was pulling Steve off the ground after he’d lost a fight with some other boys. They both have a white star on their left bicep. 
• Bucky and Natasha got theirs in the Red Room, and both had them burned off a dozen times before the Red Room finally gave up and just fried them out of each other’s heads. The marks didn’t disappear with the memories, though, and they both have red hourglasses on their stomachs. Bucky shot Natasha right through hers, after which she remembered him. She still hasn’t figured out if that was him remembering her, though. 
• Steve and Sam’s marks came in on the first morning when Steve was pulling Sam off the ground, a dark gray wing on their right forearms. Sam made a dumb joke about “on your right” and Steve tried to laugh, but was thinking about Bucky pulling him off he ground. 
• Steve and Natasha didn’t get theirs until the kiss on the escalator. It is, in fact, a black kiss mark underneath their left ears. Natasha thinks it’s hilarious but also is kind of annoyed it’s so visible. At the same time, though, it is STEVE so of course it is, she thinks. 
• Sam and Natasha got theirs in the helicopter. It’s Steve’s shield on the inside of their left elbows, which made him make a very undignified noise the first time he saw it. Very. Undignified. 
• The paint on Bucky’s metal arm started bleaching out the first time he punched Steve in the face with it. It’s an ugly streaky pink right now, most days. He doesn’t think about it very much. 
• Sam and Bucky still haven’t actually touched, but at this point, Sam knows it’s coming. He’s just not sure if Bucky knows it’s coming. 
• Bucky does not know it’s coming. Bucky doesn’t even remember Natasha, although obviously the scar in the soulmark on his stomach means the person it belongs to is already dead anyway. Bucky’s not even sure he believes the museum about Steve. 
• The paint on his arms’s a little paler, lately.
