Well kigo, i don't know a "petit-scarab" and i don't know if he's related to Tioscarab. All i know is that Tioscarab don't uses speed mod, he's just a great an fast wiper, so i doubt there's a relation between them if petit-scarab is a real cheater. Maybe a guy inspired by Tioscarab's name like the "assayyeah"guy was inspired by Arnaud.
Or maybe he's Tioscarab's little brother and is better pilot than his elder
