Coulson just smiled at Ward's 'bet', quietly making a note to maybe show the other man exactly what he was capable of when he wasn't the one issuing orders. He hadn't survived being a field agent for over thirty years just because he blended well into the background. That had helped, sure, especially in undercover assignments, but Phil liked to consider himself just as capable as any field agent of his rank even if he hadn't really had the opportunity to utilize those skills since New Mexico.
Ward was right about one thing, though. He did want to rant. There were a lot of things built up in Coulson's head, things that were all reflecting off and conflicting with one another, and it was making him antsy especially now that Ward was in front of him. But one thing about Coulson was that he did have a modicum of restraint most of the time, so he moved, motioning for the bench that he'd vacated. "This is probably going to take awhile. I imagine we both have plenty to say." The polite thing probably would have been to wait for Ward to sit down first, but Coulson wasn't feeling particularly polite right now. And if Ward wanted to keep standing, that was fine by him.
Looking up at Ward, Coulson turned everything over in his head, searching for the right way to start off amongst the clutter and confusion and anger, and taking a slow, deep breath, finally decided to start off the the easiest, simplest, and most painful truth of the whole thing.
