Can someone answer this...(SPOILERS)
I think I missed something with the time heist. Future Nebula is captured and held by past Thanos. Past Nebula takes the PYM particle from future Nebula and a piece from her head to assume her place. Past Nebula then gives the PYM particle to past Thanos so she can bring him and his army to the present.
How is past Nebula able to return with the rest of the travellers to the present if she gave Thanos the PYM particle? There was only enough for future Nebula to go into the past and return. Logic would dictate only Nebula or the army, "Thanos's ship", could return not both.
