Season 6: Episode 23 - Landmarks

Landmarks: Ted must decide to testify whether or not the Arcadian is a landmark in front of the Historical Preservation committee. While professionally he believes it is an eyesore, his personal conflict is between siding with his girlfriend Zoey or his best friend Barney. Ultimately, he realizes he must do the right thing and advocates the building's destruction but is blindsided when Zoey produces an audio recording of Ted saying just the opposite. Ultimately, when "vandals" remove iconic stonework from the building the committee decides it is no longer worth preserving. Ted also realizes after her betrayal that Zoey is not the woman he will spend the rest of his life and breaks up with her confirming she is not the "Mother" in this story.
