S2E4 · Every Day a Little Death

Billy arrives home just in time to save his dog Gordie from the fire that's engulfed his apartment, and ends up rooming with a reluctant Danny until he can find a new place to live; when a teething Alicia keeps her father up at nights, an exhausted Alan is thrilled when Diane offers to help out; when a racist teenager on the transplant list refuses the heart of a murdered black teenager, the hospital offers it to another candidate, but the boy's mother sues to have the heart transplanted into her son; Alan decides to get back into the social swing by asking Diane out on a date; Kate's inattention to pre-op labs results in the post-op death of the transplant patient; Danny overcomes his dislike of Gordie long enough to notice that he's critically ill, and by acting quickly, saves the dog's life.
