Bruce tried his best to make sure all of the people in his life had a birthday to remember,every year no matter what. He always made sure that everything was absolutely perfect. So when he couldn't find you anywhere he was surprised. Alfred and the rest of the bat-family had come over to celebrate you,so where on earth were you? He finally found you in the cave working on a case. He spoke up."You should be getting ready. Actually,you should be upstairs right now."
