Howard and Bernadette

Howard, who initially fancies himself a ladies' man, starts dating Bernadette, a microbiologist who worked with Penny at The Cheesecake Factory, and the two become engaged and marry in the fifth-season finale as Howard leaves for his mission to the International Space Station; NASA had first cancelled the flight and then moved it up, so the couple moved the wedding forward. In season nine they announce that they are expecting a baby, and they go on to have two children. After the death of Howard's mother, Stuart keeps living in her house with Howard and Bernadette until he finds a place of his own, and the couple gave Raj his Yorkshire Terrier, Cinnamon.
