I also really liked the interactions between Simeon and Greer and look forward to seeing how that rivalry builds. What is happening to Chloe is becoming rather interesting. They think she is under alien influence (From Space) and try to cure her via the interface chair. That doesn't work and it looks like Rush might bring Chloe in on his little secret. She wasn't all that interesting last season. She's very interesting this season.
There is definitely an ongoing story arc that builds up to the midseason two parter, "Resurgence" & "Deliverance".
IMO, "Cloverdale" is ok but the next string of episodes, "Trial & Error", "Greater Good", "Malice" ""Visitation", "Resurgence" & "Deliverance" and finally "Twin Destinies" are all excellent episodes with some big plot developments. They might be SGU at its best.
In fact, "Twin Destinies" might be my favorite SGU episode.
