Keegan Allen (Pretty Little Liars, Walker) brings his cheerful and bright attitude to this week's episode and discusses his experience as a hopeless romantic, his teenage angst, and how he’s managed to stay on the ‘straight and narrow’ avoiding downward spirals in this industry. Keegan opens up on his relationship with his late father and how he’s still been able to connect with him even after his passing. We also talk about how Pretty Little Liars’ success coincided with the birth of social media, drama with other actors on set, and growing up in Hollywood.
