Every show in this series ends in a cliffhanger. But when the next episode starts, the shocking new issue is not addressed or acknowledged, and things plod on normally as if nothing ever happened. Like Left Hanging, but more likely done for viewer retention than as an oversight. The new information may be picked up and addressed later in the episode (probably with a reminder since we had a week to forget about it), but it never seems so crucial or urgent as it did at the end of the last show! Sometimes the only thing that drives the series story arc forwards. One. Cliffhanger. At. A. Time.
