Mob's attitude seems to change once he hears what Dimple says. Mob ends up apologizing to Dimple because he had gotten carried away from the thought of being popular and didn't hear what Dimple had to tell him before.
You better realize that 
before you get hurt.
حريّ بك أن تدرك ذلك قبل أن تتأذّى
Mach dir das klar,
bevor du verletzt wirst.
Asúmelo antes de acabar herido.
Asúmelo antes de acabar herido.
Meglio venirci a patti, prima di farti male.
É melhor perceber antes que se machuque.
Очнись уже, пока не пострадал.
