They traveled to Switzerland, only to learn that Ra's was dead. However, Blaine and the rest of Batman's team where shocked to learn that Ra's had somehow returned to life and they were attacked by the crazed villain. After the attack, Blaine and Batman took their injured friends to a medical center and Blaine stayed with them, leaving Batman to face Ra's al Ghul by himself.
Eventually, Blaine returned to Gotham, where would often provide his scientific knowledge and assistance to Batman, whenever it was needed.
He was later murdered by his business partner, Dr. John Pearson, a computer programmer who had needed money and had sold copies of Blaine's plans on pluviculture (the science of rainmaking) to Qayin.
