I won't lie...i skipped through this episode a bit.

Essentially, Xu Er is captured with Dr. Love/brought back,

Cousin Quian Quian is to be the new concubine--Housekeeper swears he hates his aunt now and we learn that it is because he feels making his sister a concubine diminishes him in the eyes of Li quin, whom he is obsessed with and he slaps his own sister

I almost pity Housekeeper--he drinks up every bit of kindness our lady directs towards him like a puppy..

Our hero is now in charge of the Bureau of Weaponry as well...
