Okay so I was a little confused about a small detail that I noticed...So Nero destroys Vulcan because he believes Spock caused the destruction of Romulas. In the movie, when the Enterprise crew goes back to find the whales, the movie starts off with the crew on Vulcan with the stolen Klingon spacecraft, also Spock is talking to his mother as he regains his memories. How can that happen if Nero destroys Vulcan and Spock's mother dies in that event? Also, in 'Star Trek Nemisis' the movie starts with scenes on Romulas, but it was destroyed, how can that be?
