Gizmo was going through a lot and he couldn't take anymore. His best friend Tech ( Valerie_Wolf172 ) is dead and he felt it was his fault. He broke Mint's heart and he felt she hated him. He had an unstable personality that couldn't take anymore. So......he shot himself.....in the middle of of his lab. Lucas came home and found him dead. There was a note that said "Far but never gone ~Gizmo".
