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.
It might have been group hypnosis, then...
...لعلّه كان تنويماً مغناطيسيّاً جماعيّاً إذاً
Dann könnte es eine
Gruppenhypnose gewesen sein …
Podría ser hipnosis masiva.
Podría ser hipnosis en grupo.
On a peut-être été victimes
d’une hypnose générale…
Potrebbe essersi trattato 
di un caso di ipnosi di massa...
Deve ter sido uma hipnose em grupo...
