John knew he was taking a risk by doing that. And yet he had no other option but to sleep.
He couldn't even raise an arm to fight or focus enough to use any ability properly. Going on to fight the invasion would end in disaster.
So he lay on the ground, closed his eyes, while hearing Elena and Ben discuss what to do in case they got attacked.
It went without saying that Mark would come and hit them while John was asleep. Ben suggested using their defensive weapons if things reached this far, but Elena stressed not doing it.
On top of that, they didn't have any chance to do what they agreed upon. The attack came suddenly, and they couldn't even prepare anything related to the Ares God Paragon to frame him with everything they would do.
So they couldn't use these weapons, even if Elena herself knew how easily things would be if they did that.
