Manuel joins and manipulates the Rogers family, as Joe does to the Rojos and the Baxters. Maria's "widow's shawl" is also based on the one worn by Marisol.
Manuel fetishises his leather "killing glove" by keeping it in a musical box beside a photo of himself with Maria and Ben Caine. This is based on El Indio's fetishist relationship with his musical watch, which contains a photo of Colonel Mortimer's sister.
