Because it's very cold, Arthur gets to sleep in Carrie's office, which is right across Doug and Carrie's bedroom. Doug doesn't like this and can't wait for some warmth so Arthur can get back to his basement.
Carrie decides Arthur can temporarily sleep upstairs in her office - which is across Doug and Carrie's bedroom - because it's too cold in the basement. Doug doesn't like this because he's afraid Arthur will stay in the room. Carrie convinces Doug he will leave when the weather gets better and when the weather finally gets balmy, Doug and Carrie are very curious as to what Arthur will do.—Marco van Hoof <k_luifje7@hotmail.com>
