It's been a busy 9 months for Zak. He developed a game of some sort that has made him millions of dollars; founded and staffed Zakiks Studios; and moved from his parents' house into a 12th-floor luxury apartment. Meanwhile, Iris Skyped with her other ex-boyfriend twice, and Mary went on a four-day cruise with Toby. If Iris and Zak get married, will Zak age at a faster rate until he catches up with her? Will Iris and Tommy have to visit him once a week in the nursing home?
