Well ... that's one way to end a season.
Lost Girl Season 4 Episode 13 was a heartfelt finale with touching moments between Bo and her friends, but beyond that it was severely lacking.
Major plot points ended without much, if any, lasting impact.
Massimo was the biggest disappointment. He killed Hale, ate the Origin seed and was revealed to be Evony's son. Then, Massimo killed Rainer which ended the epic love story with Bo. After the build up of the Una Mens and the Origin seed, it ended with a whimper. When Bo impaled Massimo with the sword, the power appeared to dissipate.
