It's been almost exactly five years since we first saw Kristin Cavallari make her debut on Laguna Beach, and now she's back in action, essentially taking Lauren Conrad's place on The Hills. Everyone seems to be apprehensive about Kristin's return, and with good reason. During a pool party with the gang, she immediately makes a beeline for Justin, Audrina's ex-boyfriend. In the meantime, Heidi and Spencer search for their dream home, with Spencer putting a deposit down without first consulting his wife.
