In all honesty, it hadn't broken anything between them. Jack understood what had been going through the Doctor's mind -- or, at the very least, what he assumed was going through the Time Lord's mind. Jack knew neither of them were in their right mind when any of it had happened. Of course, it begged the double standard that if Jack knew the Doctor didn't have control, why did he have such an issue with his own actions?
Because this was Jack Harkness we're talking about. And Jack Harkness loves his guilt complexes. Hide them away, mind, but he has them. Why else would he have so easily let himself be buried alive by his brother? Oh he had found a tree to climb early in the morning, some place where he could sit and stare out through the branches and brood. He may also have let himself down (and not so gently either), leaving Jack's greatcoat more than a little dirty.
Strangely, he wanted to see the Doctor before he went to Ianto. In spite of all that had happened, their arguments and disagreements -- Jack still was like a puppy who constantly trotted after his master, looking for approval. Thus, when the going got bad, coupled with Jack's feelings that he had no right to see Ianto, Jack went to the Doctor.
He was a smart-ass, swiping a few different kinds of berries as he walked, holding them carefully in his hand. Wasn't like he could toss them in his pocket, hope for the best, then have Ianto send it out to the cleaners later.
Knocking lightly on the barn door, Jack slid inside and gave the Doctor one of his winning smiles. Only problem was that the expression didn't quite meet his eyes. "I am officially not the wife just because I went out foraging for food."
