Heather Mosby is Ted's younger sister and daughter of Alfred and Virginia Mosby.

Ted describes Heather to Robin by saying "it took her six years to graduate from three different colleges, during which time she wrecked two cars, got married for five days, and lived in a tree for nine weeks, only to realize that no one had any intention of cutting it down." She planned to transfer to New York University, but on the day of the admissions interview, she sold the furniture in The Apartment so she could fly to Spain and attend a Nine Inch Nails concert. She was also caught for shoplifting in April 2008.

Ted is shown to being protective of his younger sister, making a point to keep her away from Barney to prevent her from being seduced by him. Despite this, the two met in December of 2008 soon after Heather arrives. Lily discovers the two half-dressed in Barney's office and relays this to Ted, who becomes furious and disappointed at the two for their actions. It is later revealed that Barney and Heather did not sleep together, instead taking advantage of both Lily and Ted to prove that Heather had matured.

Heather decided to pursue a career in finance and move to New York City, and asked Ted to co-sign her lease. Ted wouldn't sign the lease, believing that Heather was still immature and irresponsible. However, he came to realize that she had grown up, and agreed to co-sign her lease.


Notes and Trivia

  • Heather's first mention is when her and Ted's parents, Alfred and Virginia Mosby, ask him in Brunch​​​​​ to not tell her about their divorce. Ted tells in Single Stamina​​​​​ of how he celebrated Heather's marriage with her despite disapproving of her husband ("Sandals and socks; come on, buddy."). She is also mentioned in Stuff​​​​​.
  • In Dowisetrepla​​​​​, it is revealed that she and Ted used to be detectives by the name The Mosby Boys and solved the case of the missing retainer.
  • Heather's only appearance in the series is in Little Minnesota​​​​​; however, she appeared off-screen in Home Wreckers​​​​​ at her mother Virginia's and Clint's wedding. Heather apparently did not attend her brother's 2008 wedding to Stella Zinman in Shelter Island​​​​​, as Robin had not known much about her before meeting in person later that year.
  • Ted explained that Heather once sold the couch in The Apartment. This may be a retroactive explanation for the unexplained couch switch between Come On​​​​​ and Where Were We?​​​​​.
  • Despite moving to New York, Heather never appears in the series again. While it's possible she was present at Ted's wedding to The Mother, she wasn't shown.
