Mack (Rachel Griffiths) prepares the camp for the annual CIT Parents’ Weekend. Her hands are full with Zoe’s (Carmel Rose) high maintenance mother Bethany (guest star Neveen Hanna, “Deadly Women”), and Buzz (Charles Grounds), who rebels against her punishment for the drinking incident on his birthday. Marina’s (Lily Sullivan) flamboyant mother Crystal (guest star Kellie Jones) arrives unexpectedly at camp and drops the bombshell that things with her boyfriend are over and they now have nowhere to live. Kip’s (Thom Green) dad Larry (guest star Paul Gleeson) hopes to spend some quality father-son time together but his over protectiveness becomes a problem when Cole (Nikolai Nikolaeff) recruits Kip’s help outside Little Otter. Meanwhile, Roger (Rodger Shepherd) inadvertently reveals Sarah’s (Dena Kaplan) secret affair with Miguel (Juan Pablo Di Pace) and Kip has a health scare that ultimately reveals his battle with cancer to the group.
