Couldn’t he have just summoned them back?

Then they're gonna have to walk all the way there again to rescue their families and face the monster again

Oh yeah, I guess it is a time sensitive mission. He just looked so desperate I was confused, but it makes sense if he was torn because of that. Since they’re all desperate to find their families…

I was thinking the same. Or make his pocket skill bigger and swallow the car like he does for items.
