Junior
Junior, Kevin and Karen's youngest child got his nickname by being, well, quite young.
He's a nervous little fellow, having Tourette's syndrome, so at times can be quite confronting for some folk, who are usually trying to understand everything about his hobby of beetle fighting.
Junior loves chatting all about beetle fighting, but amazingly not many people want to hear his descriptions of it a second time.
Where and how conceived... His brother and sister are a lot older because he's an accident...
A school story?
