As Ray's relationship blossoms, he begins to resent taking his pills, preferring to trust in the soothing properties of love. Over time, this decision has disastrous effects on all three relationships: the relationship between the brothers, Ray and Laura, and Pete and Mandy. Ray may cause disruption, concern and distress to those close to him but that is only a fraction of the distress his condition causes him. In the end, it is the relationship between the brothers that is central to the film. Pete is long-suffering but, despite all his frustration and resentment, his loving commitment keeps his brother from serious harm.
