The Pilot

At the end of the show, after Casey, once again, was inspired by sports and regained his confidence in the friends around him called for Dana and lighty kissed her on the cheek.
Casey (to Dana)- "*No one* can produce this show but you
."...
Casey then tightly hugs Dana in a sweet moment of appreciation
Dana (choked up by Casey's "gesture")- "You have 9 minutes. Somebody get him a new shirt."
Casey- "What's wrong with my shirt?"
Dana- "You got my mascara on your collar."
I was surprised by this once I first saw the Pilot (after seeing many of the later episodes), because I never expected Casey to be that, I don't know... sweet, I guess. After watching him furiously moap around while Dana was dating Gordon, I never realized how far those two go back and how deep their friendship was. That's the reason why I love that little sceen at the end, and that is why I'm always facinated by the emotions that run through them.
