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.
Back then, I thought 
I could use this guy...
...آنذاك، ارتأيتُ أنّ بمقدوري استغلال هذا الفتى
Damals dachte ich nur,
ich könnte mir das zunutze machen,
À ce moment-là,
je pensais pouvoir le manipuler,
Allora pensavo che avrei potuto usarlo...
Foi quando eu percebi que poderia usá-lo.
Я тогда решил, что однажды
 он может мне пригодиться.
