The most exciting thing about this episode was the cameo by the boom mic around 19 minutes into the episode (at the top of the frame when Geralt and Triss start walking down a hallway in Kaer Morhen, right before she propositions him). Otherwise, this installment meets the usual standard set by the show of insipid plot points and reducing characters to one-note puppets. Jaskier's song is pretty good, though.
