Yeah, Jonny really lost his mind in the finale, didn't he? Lol.
On that subject, this is something I learned a while back: when you think about it, none of the cul-de-sac kids seem to actually outright hate the Eds; on the contrary, some of them actually seem to be on friendly terms with them: Jonny seems to like hanging with them, Rolf never seems upset whenever they pop up on his farm, and Nazz will even talk to them (even though it makes them nervous). The thing is Kevin. Kevin is the one who hold contempt with them, but at the same time, he's the cool kid, and when your a kid, you always want to be able to hang with the cool kid, so if Kevin's going around calling them dorks and trying to avoid them, the other kids are going to do the same so they can hang with Kevin - it's typical kid stuff.
And even so, Kevin doesn't seem to mind Double D, since he's arguably the "normal" Ed; Ed and Eddy he clearly has issues with, and it's kind of understandable, given he's often the target/victim of Eddy's scams, and Ed's just a idiotic monobrow who messes things up.
And if you even think about it more deeply, I think Eddy is the one who ruins things for everybody . . . remember when Ed was trying to act all cool and hip and Jimmy didn't realize it was him at first? When he does, he briefly panics, and looks around asking if Eddy is around, but when he realizes Ed's alone, he brings him alone to hang with the others.
