He’s Tad, the new lifeguard, and just the sight of him reduces the normally fearless Andrea to a babbling wimp. The Friends all try to help her out, with less-than stellar results, each attempt resulting in increasing mayhem for Tad until he’s terrified of Andrea. Then Andrea discovers that she’s been mooning over the wrong boy all along!

But after nearly getting caught by the neighbors, they come up empty and decide it’s all just Emma’s imagination. Meanwhile, up in Maternity, Sophie’s having a baby! The girls run out, leaving Emma alone. And that’s when the bad guys decide to pay Emma a visit...
