Yeah! Like each day they have to move! So they don't get caught by the rebels.

Oooo no no I like the idea! What if the soldiers raid the home, take him for questioning? Maybe we could have him killed and Ethan uses it as an opportunity to take over? Perhaps Iris doesn't even know he gets killed until back in the capital? Thay would make things quite interesting! 

I can just imagine Atlas' reaction to finding out he is gone, just when they thought they had Cas to rescue haha.
