An art trade with a deviant on DA, practicing manga coloring for the second time.
Her fancharacter just protected Sonic since Eggman tricked him and transformed him in his child age.
Marie (the deviant's fan character), just saved him risking her fragile life in order to save her best friend. Sonic felt really guilty and started to cry as a baby. She tells him not to worry, because she will do the same as he does everyday: Taking all risks to keep its beloved ones safe.
