During that time, she’d kept to herself and twitched with anticipation. She couldn’t wait to get the vials. She’d go straight to Nurse Karen, get a shot, and be home two hours later. Wednesday after classes, Mr. Jones announced that there was going to be an assembly near the koi pond. The students were all going to learn an “Aloha” song to greet their guests on Visitors’ Day. It was just the distraction Megan needed. She caught the first few notes from Mr. Jones’s ukulele as she entered the Bs’ room. She knew that song from her family trip to Hawaii. There were at least three verses. Megan felt confident that she had plenty of time. Moving the crate was impossible. It was too heavy. So Megan had brought an empty backpack. It would be easier to simply take all the vials and put them in the pack. She’d seen Brooke carrying them out of the research center and she wasn’t hunched over, so the crate must have also stored the notebooks and research details the doctors had compiled.
