Jill Finch or Howie as she's called is a 9 year old girl who's always asking how?
Howie is the assistant to Alvin Ackerman and before Alvin was found she was the assistant to Keung Sakurai. She always helped out in Ron's lab and does the same for Alvin. However since the Ackerman family's absence Howie had grown apart from them. Refusing to let herself get as close to Alvin as she was in fear of something happening to him again. Although she doesn't show her fear Keung already knows that is what she's doing.
