No more wise old mentors. From now on your mentor options are
1. old mentor that turns out to have at least the same amount of chaotic dumbass energy as the protagonist
2. mentor that is the same age or younger than the protagonist and is only in the position of mentor because they have experience with one specific thing, but in every other respect they are just as young and dumb as the protagonist is
actually there’s a third option
3. mentor who is technically an adult and is Authoritative in the eyes of the teen protagonist but actually they’re like 31 and their internal monologue is just “AAAAAAAAAAAAAAAAAAAA” all the time. bonus points if their mentorship consists of giving the protagonist bad, morally dubious, or legally sketchy advice. Bonus points if they are internally like a super attached parent and have mega anxiety over their doe eyed teenage hero child. Extra bonus points if you manage both of those last two things at the same time.
