Barry grew up in poverty, frequently becoming sick because of poor living conditions. He developed a horrible fear of germs and bacteria as a result of the diseases he contracted. He didn’t get along well with other children and was very irritable.
Uni grew up a bit poor too, sort of a loner away from other kids, keeping to himself- he was bullied constantly and developed very bad social issues because of it. He did have a few friends though, a small amount, but still something
1. Yes and no for one, yes and yes for the other (not specifying which)
2. He didn’t really need them, he went through a kind of phase where he dressed very hipster-like and sort of like a grandpa. He grew out of it for the most part tho.
