Early in the movie, Tom (James Marsden) is concerned about Sonic's well being. After settling into Green Hills following the events of the first "Sonic the Hedgehog" movie, the blue speed demon has been having trouble finding his calling; a wannabe superhero, the hedgehog goes around bungling crimes in progress, sometimes saving the day but (as we see in Seattle) often in the most expensive, ineffective ways possible.
In an attempt to be the hero he thinks everyone needs him to be, Sonic is finding himself rudderless. But Tom tells Sonic that his time will come, that fate will tell him, rather than him making the moment happen. This goes on to be one of the relevant themes of the movie and what motivates its main character.
Tom is concerned that Sonic needs to find friends and peers that are more like him, which ends up happening when Tails and Knuckles enter the story. It is only by the end of the movie that we see this journey completed, though. Sonic, Tails, and Knuckles have formed bonds and matured together for a greater purpose — and as the film teases a new threat for "Sonic the Hedgehog 3," they stand united to battle it.
