I love this episode. Phoebe is her usual hilarious self and Chandlers middle name is revealed to be Muriel. This is a great little addition to the story line.
However, we also gain an insight into Ross and Rachels relationship. Ross is not, at this point, in love with Rachel, he says \"I cant force myself to fall in love with her again\" yet at the end it is clear that Rachel is hopeful for something more with Ross, and her hopes are dasked when she sees him with Mona.
Ross and Rachel are destined to be together, this episode just shows another of the complications on their way.
