Diane receives news from her family back in Boston that requires a trip home.
This is an enjoyable episode focussed on the character Diane and I find the scenes involving her family background are the strongest. There is a mixture of dark humour, funny banter between characters and upsetting, dysfunctional family moments that work very well. Bojack fits into these moments quite well as his character offers a good honest summary of her life at a well timed moment. There are also some good dialogue exchanges involving her and her trashy family.
Although the subplot back at Bojack's house involves a reasonably funny concept, it is essentially a one-joke thread which for me is not as funny as the writers probably think it is.
