30Hurt: Ross Said Rachel's Name At His And Emily's Wedding
Originally, Rachel wasn't planning on attending Ross and Emily's wedding. She did change her mind, though, but she didn't go through with her plan to tell him she still loved him. However, she still ended up interrupting the ceremony in a way because Ross said her name instead of
Emily's during their vows. Later, they tried to play it off as though that happened because he saw her.
What happened next was what hurt the series. Somehow, Emily became the bad guy, demanding Ross never see Rachel again if they were to be together. Soon, she was just “that girl he once married in London who became his second divorce.”
