–Lainey’s main catchphrase
Lainey is sometimes kind and spent most of her time with Barry. When she went to college, she was usually kind to both Ericas, but seemed more snotty to Barry and Adam. With being popular, she seemed sometimes like an antagonist to Adam, with calling him "geeky" and "nerd". It is clearly shown how Lainey's personality changes throughout the plot of the show. In the finale of Season 5, Barry and her share a dance and Barry brings up the idea of marriage, and Lainey accepts the idea, which makes them engaged.
Lainey is best friends with Erica and is engaged to Barry. It is revealed that her mom left the family, leaving Lainey's father, Bill Lewis, to take care of her, even though Erica mentioned Lainey's mom making Thanksgiving Dinner in season 1.
