He was a little surprised when Kara just curled up next to him, but he smiled faintly and wrapped his arms around her to hold her close after a few long minutes. Bucky appreciated that she was so forgiving but he couldn't help the pit in his stomach at all the things he'd done as the Soldier there. "It felt like what I could be," he replied quietly.
That was what scared him the most. Especially what had happened between himself and Natasha. That wasn't so far outside the realm of possibility and it was something he'd thought he might have wanted for a brief moment when he'd first arrived. It wasn't possible here, not with Kara and Bruce in the picture, but that didn't stop him from feeling guilty that he remembered what it all felt like courtesy of merging with his alternate reality self.
"I love you too. That hasn't changed. It's not ever going to change." Bucky was always going to love her, whether she was right there next to him or if she was sent back home. "It's just hard to reconcile everything I remember from there with what's real here." He had enough problems with his memories. This was just messing with him more.
