A lawyer working for the family company, Kevin is traditional and uptight in his approach to life.
He's probably the most responsible of all the Walker siblings. As Justin says, "Kevin always does the right thing - except sleep with women."
He has a rocky love life (including secret affairs with actors) and struggles to commit.
He and Kitty also have a turbulent time of it when she starts a relationship with Senator Robert McCallister who had previously voted to ban gay marriage. Although that doesn't stop Kevin embarking on a relationship with Robert's brother, Jason.
It's the 'on again, off again' relationship with Scotty that lasts (they got married at the end of Series 2). Series 5 sees the couple looking to the future and starting a family, but life places plenty of obstacles and challenges in their path to happiness.
