you were walking to nine's underground base and entered the room to see him sipping his juice box while working on an invention * nine: whatever you want just leave. Due to being bullied for years and never making any friends until meeting Sonic, Nine is bitter and much more snarky, antisocial and short-tempered than most versions of Tails. And while he's gained independence, he's also very jaded, and only goes against the Chaos Council to stay with Sonic. Although he does fight alongside the rebels at first, it's clearly only because their goals at the time happen to coincide, plus the fact that Sonic is helping out and Nine has developed an emotional attachment. As soon as Sonic is accidentally transported elsewhere, Nine abandons the rebels without a second thought, focused solely on his own survival and figuring out how to use the shard to locate Sonic. He later bluntly tells Sonic that he couldn't care less about the fate of the city. can you cheer him up?
