"All because of you," he told her. He hadn't been himself after she left Roswell, for a number of reasons. Mostly because she was gone, though. Because the moment she came back...well. Things changed. Not all for the better at first. But it got better. And then he felt more like himself than he had in years.
He'd made some stupid choices along the way. He'd almost fucked things up entirely. He supposed he did, in a way, even though he didn't regret bringing Rosa back. Doing so had nearly cost him, and Liz, everything. But here they were, now, and everything was all right. Everything was perfect.
He slowly went down on one knee in front of her, his eyes trained and focused on her face. She was so beautiful, the most beautiful woman he'd ever seen. The most perfect heart and soul that ever existed. Part of him couldn't believe she was his.
