Dean closed his eyes, leaning into that touch. How could she say that it didn't matter when he had done something so truly awful? How could she still love him after knowing what he had done? He wanted to murder Lilith with his bare hands for telling Jo that, because the last thing he had ever wanted was for her (or anyone really) to find out the details of his stay in the pit.
But she had just gotten back, and he told himself that now wasn't the time to burden her with explaining just why she should probably be worried, why things HAD changed.
He sighed softly, turning his head to kiss her hand. "I love you too, Jo." He took her other hand, squeezing it tightly. For now he was just going to focus on being there for her, on helping her recover from the physical (and less obvious emotional) wounds that Lilith and her henchmen had inflicted. Selfishly, he too needed time to recover, to have her at his side again. Then, later, when she was well...well then he would try to find the words to explain what he had done, and why she should look at him differently.
