• Enterprise deploys Echo Two, one of a series of subspace amplifiers that will allow more frequent, near real-time communication with Earth. The aliens destroyed Echo One and Echo Two, but they deploy a replacement.
  
• Enterprise was designed to carry three phase cannons, two forward and one aft. Because they left space dock early, they were not installed. They left dock with one prototype phase cannon, and built the other two.
  
• Malcolm's favorite flavor of cake is pineapple.
