Aww, this is touching. <3

Very touching. Shantelle needs cuddles >w<

Did he had an accident on the motorcycle?

Speaking of this illustration Sheas was depressed but tried to get through everything alone. That caused his nervous breakdown and ended with a heart attack. Shantelle got scared because she understood she could help him to get through, but she didn't even know what was happening to her brother. His family discovered his troubles only when it was too late. This situation made Shantelle more caring and attentive
The story of Sheas'es depression was told in "Prehistory" - an old 10 page comics http://www.furaffinity.net/view/28352835/
And some of the heart and nervous problems will show up during "The Fate!". But I'd say Sheas is healthy (mostly) and surrounded with care now)
By the way, "The Fate!" starts right after Sheas has just recovered. This is why he seems to be very closed at the beginning

However, you were close - he had a motorcycle accident too. Though this ended only with a damaged hand for Sheas, he got no serious injuries. But this was his one and only accident and he left motorsport right after it, because he didn't want to take risk

I read the story and poor guy.But there are attention whores out there. He was unlucky to meet one.

I, and hell most of my characters, can relate to this one. The good characters fears tend towards "being alone" or "Losing a loved one" for their greatest and deepest fears.

Evil characters not so much.
