Gateway: An entry to a place
Chelsea: An Anglo-Saxon, American name meaning port; an English name meaning seaport
Gladys: A Latin and American name meaning sword
- This may be a reference to Valve's Portal series, given the names used by the household members - Chelsea, like Chell, the protagonist, and Gladys, like GLaDOS, the villain. The name Gateway is a synonym of Portal, the main element of the game. Also, the household's description is a reference to the game, just inverted.
