I was surprised (and impressed) that Welling was in so many scenes, since he was also directing. Clark has been reduced in screen time somewhat the last few episodes, so I figured he'd be in even less, but nope!
Welling did a nice job. The performances seemed somewhat less standard and a little deeper. (Of course there was much more story going on as well).
I love how all the people who have been telling Clark to "stand up" are looking more and more like selfish and unrealistic idiots as the season progresses. (Oliver and Tess especially look more and more shallow about it.)
Clark has his own timetable and instead of looking like he's reticent (as some have claimed), he looks more and more like he has a long-range plan. And his arguments are finally getting through to his would-be cheerleaders.
Good episode as the set-up for the season finale.
