Arthur's new sister remake

It began as a normal day in Elwood city, nothing out of the ordinary everyone going where the needed to be, but I can assure you the day wouldn't end normally. Arthur and Buster sat on the couch watching a bionic bunny episode, while DW sat on the floor playing with her Mary moo cow doll, David emerged from the kitchen wearing his apron and said to his children.

"Arthur, DW, could you please let me know if the doorbell rings, I think May comes home today"

"Will do dad" Arthur said not looking up from the TV. That's when Buster asked Arthur.

"Arthur, who's May"

"oh" Arthur began "she's a foster child we're taking in, I don't know much about other than she's from Arkham Massachusetts, and she's about Alberto's age"

"huh, that's" But before Buster could finish his sentence a long black car pulled up in front of the house, and two large men stepped out with an aardvark girl around thirteen between them, she was very pale and her long brown hair covered one side of her face, a large chunk was missing from her left ear and she was only dressed in a pink hospital gown. One of the men rang the doorbell and Arthur yelled "dad the doorbell's ringing", David once again came out of the kitchen and walked over to the door to talk with the men, that's when Buster chirped

"She's an alien"

"What do you mean" Arthur asked

'the signs are all there" Buster began "the black car, the two large men even her clothing she's obviously an alien and your family was chosen to hide her from the illuminati"

Arthur sighed and said "does everything have to be aliens with you"

Buster gave Arthur a look and said "I say we eavesdrop on your dad and find out some juicy alien details" with that Buster stood up from the couch and ran over to the door, he crouched behind wall and listened, Arthur soon appeared not wanting to be alone with DW joined buster behind the wall, and listened as well. They could hear one of the men on the other side of the wall say

"and give her this if she haves nightmares and give her this if she gets nervous"

Buster peaked around the corner and saw one of them men holding a paper bag, he could see a collar and leash sticking out of it. Suddenly he and Arthur tumbled forward and came face to face with the "Alien" and her "government buddies".

"oh Arthur, I'm glad you're here" said David "this is may".

The girl gave them a small wave and then said weakly "good to meet you" before immediately shrinking back, but not before taking the bag from one of the men, Buster stood up and brushed himself off before saying to Arthur "I'd better get home we can discuss the Alien later". With that buster ran out of the house and down the street, Arthur sighed and walked back into the living room. Soon he went back to his room to do his homework and found the girl sitting on his bed reading a book, her bare feet dangling off the side. When she saw Arthur however she immediately stopped and stared at him with fear in her eyes "Did they send you" she asked, "did who send me" Arthur said, "the old ones" the girl said "oh no I've said too much they send lightning to me when I talk about them" with that the girl put down the book and hid behind Arthur's bed repeating a prayer of some kind in frantic whispers, Arthur would've written this off, but he saw something that made him scream the book the girl had been reading was floating in the air.
