Back on the job, Rachel (Jennifer Aniston) is still wary of Gavin (Dermot Mulroney), the young hotshot who covered for her while she was on maternity leave. To all outward appearances, Gavin is less interested in getting Rachel's job than in winning her heart -- as he demonstrates by presenting her with a remarkable birthday gift. Elsewhere, baby Emma's sexy new nanny, Molly (Melissa George), has aroused the interest of Joey (Matt LeBlanc), much to Ross' (David Schwimmer) dismay. And Phoebe (Lisa Kudrow) experiences a devastating loss thanks to a clumsy Mike (Paul Rudd). ~ Rovi
