Trivia

• Elly was the name of Dorothy in the alternate retelling of Wizard of Oz

Only a few frames give a clear view of the emblem atop Elly's seed before Kyubey swallows it.

Speculations and observations

• Elly's initials (H.N.K.) is an anagram for N.H.K. Since the official card states that she is a hikikomori witch, that is a double link with the manga (and anime) Welcome to the NHK
• Elly's Grief seed is not shown directly after the fight in episode four. This, along with the small barrier size, lead many fans to believe that she was merely a familiar until the official website was updated with her details. The seed that Sayaka uses in episode six was probably Elly's. Also, chapter three of the manga clearly shows her dropping a seed although the design details are different, like all of the grief seeds in the manga version.
