How I Met Your Mother: 10 Best Characters Who Appeared After Season One

10. Patrice

The inclusion of Patrice on this list is proof that it was not written by Robin Scherbatsky.

Patrice, played by Ellen D. Williams, is Robin's co-worker at World Wide News. She appears throughout Season 7, displaying kindness towards Robin, but was always met with a rude response along the lines of, "Nobody asked you, Patrice!" Despite this, Patrice would still bend over backwards to make Robin happy.

In Season 8, Patrice and Barney start dating, and she appears to make him happier than any previous relationship. This infuriates Robin, as she had feelings for Barney. When Barney reveals to Ted his plan to propose to Patrice on top of the World Wide News building, Robin becomes upset, as this is her favourite spot in the city. She heads to the top of the building to try and stop the proposal, but Barney reveals that the whole relationship was a ruse, and proposes to Robin.

Patrice is such an iconic part of HIMYM. It's surprising that she comes in so late in the series' run given her impact on the show.
