The girl made a shrine dedicated to Arnold including a gum sculpture and that alone justifies my statement. But to elaborate further, she was constantly following Arnold around and cutting him down with insults, mainly referring to him as “football head”. Personally, I don’t think it’s just a crush. I see an aggressive, malicious, extreme fascination and realistically, Helga has psycho tendencies. If Arnold knew the potential level of danger he’s in every time he hangs around Helga, I’m certain a restraining order would be intact. Maybe if she shaved her unibrow and stopped acting like a dude, Arnold would give her a second look.
