The first episode where Lola speaks English.
The episode title, "La Serpiente", is Spanish for "The Snake."
The sewer set was so complex that the cast and crew needed maps so as not to get lost.
The 'serpiente' of the title (or 'snake' as it is in English) is Daniel's nickname for Strand.
With 1.99 million viewers, this was the least watched episode in the third season.
