Pearl worries a lot about Dia. A whole lot. He feels as if it’s his #1 responsibility to take care of him. Even though it doesn’t look like that with all his smacking and yelling at him. It’s just his way of showing he cares.
Dia is actually one of the few people Pearl will ever tell things to. Pearl tells him almost everything and trusts Dia 110% with anything he says to him.
Speaking of those types of things, Pearl has many ‘secret’s which really shouldn’t be secrets in the first place.
The first one involving his dad. He isn’t fond of him all that much, even though he seems to talk about him a bit. It’s mostly because he misses him, but at the same time is upset that he left him alone in Twinleaf town in the first place. However, when he talks about him he still says his childish “Daddy”, it’s a habit he has yet to break ever since he was 4.
Because of the sole reason he dad never visits HIM, he hates a lot of family holidays, too. The main ones being Thanksgiving and Christmas. He tries not to show it to Dia so the kid can have his own fun, but it gets a little hard to contain after a while. He usually ends up telling Dia he has to go home and isn’t coming down for Christmas and he stays holed up in his room the whole day.
It concerned Dia the first few times, but after 5 or so years he got used to it and decided not to ask what was keeping Pearl down in the dumps. So, as far as Dia knows, Pearl still idolizes his dad.
Since I rambled about that, the Second one is his scarf. Pearl loves his scarf a lot. He was given it, and he loves it as much as his best friend. If you so much as singe it he’ll kick your ass up and down the block. He bought Dia a similar scarf just so they could match with each other.
Pearl also likes to hang out at Dia’s if he can, having frequent sleepovers, almost to the point of sleeping over every other night. He treats Ayako like his own mom sometimes. However he still calls her “Dia’s Mom” to pound it in his own head that she isn’t his real mom. He doesn’t know whether she died or just left his dad. He doesn’t really care anymore, though.
