questions regarding Pym Particles + Time Vortex gps
Finally saw the movie tonight and these 2 questions have been bugging me, I did go all the way to page 8 to see if they have been answered before but could not find anything
As far as I understood the process, the particles are processed in the antman/time vortex suit as we see ant-man load up a vial and then accidentally use it up and the GPS is needed to successfully navigate the vortex. So
1. How did evil nebula return if she had left her GPS and Pym particles (they had such limited amount to begin with) for Thanos, it seemed like everyone needed their own gps device...(if you say she piggy-backed and DID leave her GPS for Thanos, see question 3)
2. How did Thanos's ship even process the particles, was the ship wearing a time vortex suit ? did they just sprinkle some Pym on the ship's nose ?
3. Ignoring the ship + pym particles issue, How did the ship navigate the Vortex ? If you could navigate the vortex without the gps and the only thing you needed was a person on the receiving end throwing random switches on a board (obviously this process does not require any sort of finesse) why did everyone need to time travel at the same time ? someone could stay back and guide everyone back by random switch throwing action. (Connects to my 1st question, If she had left her GPS then Thanos could just get to this time on his own, just like all the others got back without the need for anyone on this end doing anything..but he had to wait till she used the switchboard meaning he did not have a GPS)
I'm sorry if I am going round and round between 1st and 3rd question, making my head hurt just trying to word my questions properly to make the most sense (English not my 1st language)
