Terminator Genisys: 10 Questions It Failed To Answer
9. Why Was The Young Terminator Sent Back To 1984?
When the movie eventually gets back to 1984, theres already a good Terminator and a bad Terminator hanging around, yet we see that they still decide to send another T-800 back in time, in the form of a young looking Arnold Schwarzenegger.
If Skynet already had a T-1000 in place in that timeline, why would they need to bother sending another machine back? Was this simply a back-up plan in case that one failed, something to aid it, or was there an entirely different logic (or lack thereof) to its presence?
Maybe the whole reason it was sent back was just so that they could have the scene of old Arnie fighting young Arnie, with no real impact on the plot as such, just a moment for fans to get excited about.
