Nellie was Arro and Theories adopted child. At the moment, Nellie was being harassed by her childhood “friend”, Jaci. This is when theory and Arro come in, standing angrily.

(Theory) Oh hell no.

(Arro) We’re going down for real this time.

Arro and Theory were both much stronger, considering Jaci was eight and Nellie was stronger. Of course, they would never hurt Nellie. But Jodi? After she hurt their kid? That was another story.
