Steve reveals his middle name: Aloysius.
Steve McGarrett says that his middle name is "Aloysius". That name means Legendary Fighter, or Famous Warrior.
This is the first time McGarrett's office is bombed. It would happen again in season 9 "Blood Money is Hard to Wash".
The scene of the bomb being hurled into a travel agency producing an explosion is used again in this season's final show "6,000 Deadly Tickets", but the angle is different.
