Love is the glue: it makes people want to keep their commitment to someone, no matter what happens, just a shame that Regan and Gray's relationship was based upon agreed commitment but trust, honesty and openness was missing from the start. Commitment started when Regan took on Gray, his sister and his grandfather. Regan provided a roof for all of them, and she gave Gray a job on her farm. Commitment was shifting because love was faced with unrevealed undercurrents.
