Yeah, Randvi has only been travelling about an hour away from the airfield because then she can go "home" for a safe place to sleep afterward. (Also the last time she worked with a teenage boy the second she let him out of her sight he got murdered so even if Senku wanted to wander idk if he’d be able to lol)

I'm positive that the code for the door is someone’s callsign so maybe they can brute force it lol.
