Third Watch, Season 3

Susan (to Faith):
I've been sitting here thinking uh… what else I've could've done. What else I should've done. I knew Chloe was struggling. I saw the signs before she and Joe moved to St. Louis. But I couldn't accept it. It was too damn hard to imagine going through all that again. So, I pretended that it wasn't there. Pretty pathetic, huh? She's my older sister, you know. She was so great to me growing up. She took me everywhere. She taught me how to ride a bike, how to hit a curveball. I adored her. She was the best. What the hell happened to that sister? Who do I see about getting her back?
