The café where Richard, Pen and Jerry are sitting at the end is the same one where Celine and Jesse went to after they ran into each other at the bookstore (Le Pure Café).
The scene where Kate, Richard, Pen and Jerry, all dressed in black wetsuits, scale a rocky cliff with the help of ropes mimics the pre title sequence of The Living Daylights. The music accompanying the scene also closely resembles the score of this Bond film.
