Alex is a beloved character obviously, so getting a story about his son, who has a huge reputation to follow felt like a natural storyline.  I think the moments where Jake turns to Alex for advice were really sweet.  And of course the characters from the last series making an appearance is always fun.  Definitely heartbroken about Aline's story so maybe skip this one if abuse against women is triggering for you.  Excited to read about Jamie since they seemed to be painted as sort of opposites.
