Even though it's probably going to bite him in the ass Kaveh isn't going to hide. He's just going to go through all the downstairs rooms and have Mehrak drag all the furniture back to where the exits need to be sealed.

Ayato will attempt to find anything that looks like it won't budge to try and use it using his autumn abilities, to try and block any of the places that look like it has cracks that could lead to outside--likely heading further back and away from it to buy them time from it potentially getting out. Since Kaveh will be hanging back, he'll use telepathy to try and get him to hurry, but he has a lot more self preservation so won't hang quite as close even if he sounds frantic in his head. Since Kaveh will likely be the first to go, he'll try and find somewhere to hide after that to try and make a phone call if he can.
