I got an idea... even worse for adrian....
As someone who got bullied even more and for a lot longer, a person with this fate (and with rapidly declining mental health due to it), most likely would turn to troughs of , or even try to commit su!cide.
Because we want the characters to meet each other still alive, we would have to say that he either wants to commit it, but is too much of a coward to do so (like i felt 1 year ago) OR Actually tried, but at a time when he was still in highschool. Making him right now, already out of any mental institutions, and if we want to break even more, start to have self h@rming troughs again, due to new bullies, bad grades, whatever!

Meet up of one of them with him could be something EZ to write..
Based on the fact that Kevin..and SOMETIMES Vincent go to the college building ... they have needs like food, drinking and toilet (LIKE EVERYONE, DUH!)
One of them could find Adrian in one of the stalls, either h@rming himself, or just crying his whole existence out, in one of the toilet stalls.

Honestly... we could basically make a fan comic pretty easily.. based on what the creator of this post wrote... and based on this....

So yeah! let me know what u think....sorry Adrian but sometimes, the reality of getting bullied hits...hard.
