They don’t. You should post something in the thread saying you pupiled the other person and include the brute you want pupiled. Most of the time, they just want pupils and wont pupil you back anyway

The best way to jump in points is depending on your own pupil system. People asking for pupils around actually dont know much about the brute system. They need to reset both modem and flash cache before pupiling others, otherwise you can have thousands of pupils doing nothing.
I’d offer you a better systematic play which can make your brute have at least 10 levels in a month (depending on how much pupil you make for yourself)
