Mark desperately tries to find someone who can convince Bridget to return to her own home, while at the same time she and Rebecca begin to bond.

Phyllida, who shares a flat with bisexual Giles, straight Jonathan, and Serafina, a teacher on the verge of a nervous breakdown, finds her home life disrupted when Giles' crotchety grandfather Herbert is unceremoniously dumped on their doorstep.

Bridget finds herself increasingly attracted to the considerably younger Giles and decides to move with him to San Diego, where he was born, and start a new life there together.
