Pietro and, later, Wicked
Being here in astral form wasn't so bad, Wanda decided. She could still interact with people, even if she hadn't been able to do more during the ceremony beyond stand there slightly glowing, which actually encompassed what a bridesmaid usually did, so her limitations weren't such a hindrance. Her only regret at the reception was that she couldn't have anything to drink, but that was probably for the best after Wicked's bachelorette party, really. Wanda was just glad to be here, in any capacity, to celebrate her brother's marriage and she couldn't be bitter about the circumstances. To expect anything other than strange circumstances would have been silly; their entire lives had been anything but normal.
She didn't have a chance for time alone with Pietro before the ceremony and so she sought him out at the reception. "Well, there you are, married," Wanda said as she approached him with a smile. "I really didn't think you'd be the first down the aisle, darling," she told him, and reached out instinctively to touch his shoulder, but her hand slipped right through him.
