Anthea watched the armed officers place Irene Adler and her three henchmen in the back of an armored vehicle. Watching Mycroft quietly listen as Molly told him how she'd climbed up the fire escape and fired warning shots before the police came (even though he already knew it) made Anthea smile. He was doing his best to prove himself again to her, and she appreciated it. Seeing John and Mary tug the pathologist away, she approached Mycroft.
"Sir, may I have a moment?" Seeing her serious expression, he nodded and turned to the man he was talking to, waving them off. Gesturing to a darkened hallway, he stepped aside, letting her take the lead.
"Is something the matt-" Mycroft was cut off by Anthea pulling him close and kissing him. "I'd say not," he breathed, eyes twinkling at her in the darkened hall.
"You have something of mine," she said quietly and for a moment, he frowned. "I wonder if you'd be so good as to give it back to me?"
Slowly, Mycroft reached into his pocket, finding her wedding band where he'd placed it when he changed for the evening. Taking her hand, he slid the ring back into place on her ring finger. For a moment neither said anything, each let a small sigh, a breath neither realized they'd been holding. Eyes shining, Anthea smiled at her husband, stepping closer to him.
"You could kiss me, if you wanted."
"I do," and he drew her into the circle of his arms. "There," he murmured against her lips. "Back at last where I belong."
