So what are my characters' charms (or flaws) according to yours?

both

donnie is a loyal little boy who cares deeply about his family

don't tell anyone

smart obviously but also that!

Donnie like tell no one I love my family.

flaws though.....self-punishing, given to wallow rather than fix, and stubborn on top of all that

hey if no one else is going to punish him, he may as well do it.

sherlock: that's ridiculous
also sherlock: i deserve to go to jail for an accident i caused at age 11

Donnie: hypocrite
