Since the age of nine Ollie has had OCD, it was caused by an abusive relative of his, he has OCD that is in the form that he's scared of dirt and that he constantly thinks that he's covered dirt and thinks that if he touches someone that they'll get dirty and infected by him, so he became so scared to hold or look after Dewey who was only a few months old at the time, because Ollie didn't want to make Dewey ill or lose him. Over time with living away and staying away from the abusive relative and therapists he was able to recover and be the person he is now and the caring big brother he always wanted to be :)
I did my research so I hope I don't hurt or offend anyone.
