Ho Yay: The trio attend one of Amy's sensitivity trainings because Sonic insulted a friend of Knuckles' by mistake. Sonic knows a group hug is incoming; he lowers his eyes and tells the others in effect to just get it over with. Knuckles immediately pulls Sonic to himself, and Sonic starts staring into the distance suddenly looking rather surprised...
Informed Wrongness: Sonic is constantly seen in the wrong for refusing to let a normal guy help, calling him a "guy", then bringing him into battle, where said guy doesn't nothing but sit and watch, and calling people people.
Narm: Sonic's speech tries to be either awesome or shocking, but thanks to his repeated voice cracking, can come off as this.
Never Live It Down: Fans will not forget or forgive how the villagers treat Sonic for calling Mike "just a guy".
Tear Jerker: Sonic's rant about the villagers' treatment and quitting heroing. Roger Craig Smith's voice acting really makes this scene.
Unintentionally Sympathetic: As tactless as Sonic was in his comment about Mike, he did not deserve to be a pariah among the village. We're expected to side with the villagers because of Sonic's actions, but clearly, no one likes to see their favorite blue hero treated with such contempt. After all the crap he dealt with, Sonic had every right to yell at the villagers, his friends included for not being actual friends, and almost quitting being a hero.
Unintentionally Unsympathetic: Mike, the titular "guy" in this episode, is constantly made out to be the victim due Sonic calling him "just a guy", being brought to a battle and getting hurt because of it. Keep in mind, Mike wouldn't've gotten hurt he hadn't pestered Sonic to let him help in the battles. Not to mention, Mike is an obnoxious character who shouldn't even be asking Sonic to come and help, or simply watch the battles, so can't sympathize with him, because of how stupid he and the villagers are.
Speaking of the villagers, the viewers are expected to agree with them and think Sonic is a bad person for off handed comments towards Mike and them. The truth of the matter is, they're a bunch of ungrateful bastards, and hypocrites to Sonic, who are quick to tell baseless lies to slander Sonic, and to even blame Sonic for Mike getting hurt when it was clearly their fault to begin with. Even if they did apologize for their behavior, nothing stops them turning on him in the future, will it?
The Woobie: Sonic. His rant sums it up very well: he is hardly ever shown any appreciation for saving the village every week, and it seems that the only time that anyone notices what he does is when he does something wrong. Oh, and not to mention how quick the villagers and even his own friends are to turn on him (with absolutely no one coming to his defense)...
