him after finding out that he had made a list, on the insistence of Chandler, comparing the good and bad qualities about her and Julie. In the later episode "The One with the Prom Video" it is revealed that Ross, despite being two years senior to Rachel, had decided to be her date on her and Monica's prom, as Rachel's date had not arrived, only to be left disappointed as her date arrives and they both along with Monica and her date take off for the prom. Touched by this, Rachel kisses Ross on learning this revelation, and the two begin dating. However, they take a break from their relationship on their one-year anniversary together after Rachel's overtime work prevents them from spending time together. That same night, Ross has a one-night stand with Chloe, which causes Rachel to officially end their relationship. They get together again at the end of season 3 but again break up at the start of season 4. Some of the later episodes show them to be still in love with each other such as when Ross cancels his Discovery channel show appears to be with Rachel when she breaks her rib or when Rachel flies to London to tell Ross before his wedding with Emily, that she is still in love with him, only to realize that it would be better not to tell. However, Ross accidentally says Rachel's name at the altar, and the marriage soon dissolves. In the season 5 finale "The One in Vegas", Ross and Rachel marry each other after getting drunk in Las Vegas. This marriage ends in a divorce after a failed application for an annulment; the two sadly admit that they thought if they ever married each other it would last. In the seventh season premiere "The One with Monica's Thunder", after the news of Monica and Chandler's engagement, a passionate moment between them leads to Ross and Rachel kissing. Monica is hurt by this as she believed that Rachel was trying to “steal her thunder”. The kiss is later revealed to have happened because Rachel is upset that she is “not even close” to being engaged. At the end of season 7 at Monica and Chandler's wedding, it is revealed that Rachel is pregnant. The father is revealed to be Ross in the second episode of season 8, and Rachel tells him in the next episode.
