The two begin dating each other only from Episode 15 of Season 2 after in the earlier 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. Rachel famously kisses Ross on learning this revelation. However, they take a break from their relationship on their one-year anniversary together. That night, Ross has a one-night stand with Chloe, which officially ends 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 appearance 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's still in love with him, only to realize that it would be better not to tell.
