I have no idea what happened in the show that photoset is of, I’ve seen a couple episodes of it in the past but never got around to watching more. As for what’s happening here, I’m thinking Helga beat the crap out of some dude the other day who was making a mutual friend of her and Arnold’s miserable. Or was just being awful to them or something. It was probably someone most of the school thought highly of, so even though Helga did it for the right reasons she’s still seen in a bad light by most pple, b/c her reputation isn’t the greatest to begin with either and ppl are pretty scared of her normally. Arnold knows better tho, and he knows why she did it, and although he isn’t big on settling things with violence, he knows this was probably the only way that person would stop and tbh he was pretty close to decking them himself soon, Helga just beat him to the punch (da dum tsh). So ya, Helga’s got to deal with pple talking shit about her and she doesn’t really care b/c at the end of the day she has pple like her friends and Arnold who know better and that’s all that matters. The talk still puts her on edge tho b/c pple are feeling sorry for the asshole, but Arnold’s touch and words of affirmation melts the tension away and gets rid of the urge to punch more pple in the face.
