Just curious on peoples thoughts about this. Because when the weapon arrived at earth there was NO ships waiting for it or even around. Granted they came out of the vortex 2 million km from the planet but when archer and them return to the present there is a fleet waiting for the. Then archer blows it up and wakes up in Nazi germany.. Then Enterprise arrives and its in the past to.. so my theory is they opened up a portal into time in vortex and pushed enterprise through. Though that also means the aqua warship traveled back in time but maybe going back home put it back in its normal time. Just some thoughts as I watch zero hour. Now they do destroy an unarmed station maybe it slips into the past after that?
