- Helen is in the same class as Prunella Deegan.
- She is a fan of Henry Skreever.
- She most likely met her friend Nancy at some point during kindergarten or at the Elwood City Preschool.
- During her year as a third grader she was in Miss Sweetwater's class as seen in the episode Arthur and the Real Mr. Ratburn.
- Until recently, Helen has never been heard speaking. However, she, Nancy, and a boy can be heard laughing at the information D.W. gave them about Arthur.
- According to what Arthur said in the episode "D.W.'s Imaginary Friend" Helen is apparently D.W.'s friend. As to how or why that is the case is a complete mystery, but it can be assumed she is Arthur's friend as well and met D.W. through Arthur.
- In the episode, Love Notes for Muffy she was incorrectly mistaken as a 5th grader along with some or all of her classmates.
- Helen, Steve, Nancy, and Patrick were all seen in the commercial for Moon Boots. She would be seen in another commercial for the t.v. show Let's Talk to Some Kids, which took place during the episode And Now Let's Talk to Some Kids. This could mean she or her family in general maybe involved with commercials and advertising in some way.
- She is a fan of Persimmony Glitchet's Horrendously Horrible Happenings books.
