 Originally in the script, the relationship between the main  characters (Tulio and Miguel) was supposed to have more of an  implication, with each calling the other by pet names like  "darling". This would have heightened the tension when Chel came  between them and when the argued about splitting up. The producers  and other executives had the pet names and other references cut, but  in some versions of the subtitles (which are often taken from  original scripts), the pet names can still be seen.
