Amy Rose thinks that she's in a love triangle with Sonic and Shadow, when Sonic has been going steady with Shadow for years and has never had the slightest interest in Amy. In order to try to make Sonic jealous, Amy starts dating Surge the Tenrec, unaware that Surge is even less informed about Sonic's romantic situation and is also dating Amy solely to try to make Sonic jealous. Sonic is just glad that he doesn't have to worry about having Amy breathing down his neck anymore. Kitsunami gets suspicious of Surge's enthusiasm for the supposedly-fake relationship, and attempts to murder Amy; his repeated failures, which are largely unnoticed by Amy or Surge, result in a series of wacky misunderstandings which culminate him being best buddies with Silver, who genuinely is trying to be friendly with him. Whisper and Tangle have just been together perfectly happily together, independently of all this.
