Wanda offered her hand without qualm and at the sight of the jewelry placed on her palm she froze. For a moment she forgot to breathe. More than mourning the loss of these rings, their disappearance had been agonizing, not for what they were but for their significance.
Tony's ring was usually the only piece of jewelery she wore, had become almost a second skin on her right ring finger, and slipping it back on made her feel whole. It was comforting. Pietro's ring was symbolic of their bond and their devotion to one another, as the first had been, and Magneto had taken that and turned it into something cruel. Then Sinister had taken this one and left her bereft and powerless and alone.
Wanda felt in losing the rings that night she'd lost another piece of herself to Sinister. She'd thought she would never see them again and even if they were replaced, something important had still been stolen from her. To have them back, it was like magic. It was incomprehensible. It was Tony, perhaps unintentionally, through this small gesture still playing her valiant knight.
Wanda took a deep shuddering breath and a quiet moment to admire the two rings on opposite hands, and then she gazed up at Tony with a silly grin and shining eyes. She moved one tentative step towards him and then, without preamble, she took his face in her hands and locked her mouth with his. Her kiss was slow and passionate yet somehow desperate as she tried to convey a hundred things it was too difficult to say. Let him run away if he wanted, but not before she gave her thanks and apology in this one way they both clearly understood.
