Concept: Jason sending Tim a different drug dealer’s name every month so that rich kid Tim Drake tries to make the dealer sell to him as a test if they’re truly sticking to Jason’s no selling to kids rule.
Jason has essentially killed two birds with one stone, 1. He got to identify and take out the fuckers that were still selling to kids and 2. He essentially made sure Tim could never buy anything from Gotham’s dealers. Call it his way of caring.
To anybody else, Tim just looked like another stupid rich kid who doesn’t know what they’re getting themselves into but the ruse is up when the news starts spreading that anyone who sells to Tim Drake specifically will get their ass busted by the Red Hood. So the next time Jason sees Damian he pitches the idea up to him and the few dealers that sell to Damian get an especially slow and painful treatment cause how dare they sell to what is very clearly a 14 year old baby??
The operation is kept strictly away from Bruce, of course, until one day some reporter breaks the story about billionaire Bruce Wayne’s kids caught trying to buy drugs and all HELL breaks loose. The end result was all of them being grounded for a month after a 5 hour long rant about responsibility and damaging their civilian reputations and the entire Wayne family being blacklisted from the drug market no matter how much cash they wave around.
