Reality+vs+Illusion

The question of what is real or an illusion is weaved through the patients' state of mentality. As shown through Ruth who struggles to pretend having real coffee on stage, it is difficult for some to distinguish reality from illusion, even if it is clear to everyone else. For others, they may willingly refuse the truth and succumb to an illusion. Lewis deluded himself into believing that Lucy was faithful, when all signs such as Nick residing in the same home and Nick and Lucy spending time together, indicated that Lucy was in fact, blatantly disloyal.
