The Ex-Factor

Seth is thrown when Alex's ex arrives in town for a visit, and is even more thrown when he finds out who it is. Julie has a plan to try and save The Newport Group, which to everyone's surprise, might actually work. Lindsay sticks out when she joins Summer and Marissa for a girls night out; meanwhile, Ryan, Seth and Zach contemplate playing it safe on a guys' night in. But nothing ever goes as planned.
