Several times throughout the helicopter chase scene in Terminator 2, the T-1000 is shown with three to four hands. Why?
There are three reasons that can think of for this.
- In-universe, he is capable of growing multiple hands when necessary. We see that his form is nebulous, so this is possible. However, if he had this ability all along, you would think he would use it more often.
- It's an unintentional error on the part of the film's creators.
- The film's creators wanted him to use a gun and fly a helicopter at the same time and thought that giving him extra arms was the only way to do this. Maybe they hoped nobody would notice?
Are any of these, or something else, the reason?
