After months of stalling, last week’s “Cold Feet” jumpstarted all of the series’ stagnating season-long arcs, finally giving the show a bit of momentum. Thankfully that continues this week, with each of the threads not only progressed, but examined in a way they haven’t been for much of the season. Yes it’s easy to infer that Kristina’s impulsiveness this year stems from her cancer scare and exposure to the harsh impartiality and unpredictability of death, and we’ve seen a handful of scenes on this topic over the course of the season. But while there’s plenty to be said for letting the audience read between the lines, at a certain point a character deciding to run for mayor and then open up a new school becomes a difficult pill to swallow (for this reviewer, that point was almost immediately). Showing us Kristina’s anger and frustration over Gwen’s fate gives us the emotional background we needed for these choices and, thanks to Monica Potter’s fantastic performance throughout the episode, builds up substantial reservoirs of empathy for a character whose Mama Bear instincts toward the people and projects she cares about can quickly become aggravating.
