Bucky & Molly
Bucky could tell she wasn't totally for it and that was okay. He gave her another kiss on the top of her head. "Think you could maybe spend some more time with her in the next couple of months? There won't be a wedding if it's not an honest, resounding yes," he promised. They both knew she wouldn't succeed in lying to him about it, but he was confident Kara could win Molly over before Christmas.
"I know it's a big change, something more permanent," he added softly. "You come first though, same as you have since I got here." Steve was also first, but Steve defied ranking when it came to Bucky. Molly probably didn't know, or at least didn't fully understand just how big of a deal it had been for him when she'd just accepted his presence in her life. In Steve's life. She could have just as easily said no, been afraid, and Bucky knew Steve well enough to know their lives would've turned out very differently here if she had. He owed Molly a lot.
