Mycroft leaned back in his chair, folding his hands together in his lap as he took in Gregory's expression. Some tension left his shoulders when Gregory backed up his thoughts on not having the former Mrs. Lestrade - in fact he nodded briefly. "I am glad I chose correctly, then."

He cheated on her, she ... got angry. Took the opportunity to make some extra credit with her people by framing him for murder."

He sighed, "The reason she stayed is because she recognized me. The Tong and I are ... what would one call being the arch-nemesis of an entire organization? Nevermind, hardly matters. The point is, she stayed because she thought she could have a chance to take out me. She didn't realize the tech had stayed behind."
