Newt was left alone with the child at Queenie and Jacob's house when he brought the unconscious little Muggle here. Quinny and Jacob went to get groceries, and Newt himself was afraid that the child would be noisy when he woke up. Newt was looking at his magic suitcase and breathing heavily. The suitcase has a special switch — a muggle trap, which serves to hide magical creatures from Muggles. A non-magician who opened a suitcase could only see travel items in it, so he was not afraid to show the child what was in the suitcase... Of course, he didn't want to wake up this little sun, but because of the assignment from Dumbledore, he had to hurry while in America. But.. Now he'd better keep an eye on the sleepy little Muggle lying on Queenie's bed. What should Newt do with her?? He looked around Queenie's room, and didn't know what to use.. There were a lot of women's things around that he didn't know how to use..
