RESCUE ME (Tuesday, 10/9c, FX)
If it weren't for bad luck, this firehouse would have no luck at all. In the emotionally taut (but also darkly funny) season finale, we learn what happened to Tommy Gavin's rookie-firefighter godson Damian, last seen fallen under heavy debris in a warehouse fire. While his own neglected family beckons, Tommy drowns in guilt over the latest mishap. Is there no rescue for these flawed heroes? We'll find out when the show returns for its final season next year, with the finale set to coincide the 10th anniversary of the 9/11 attacks that inspired the series.
