My theory is that he is the strongest out of all of them as well he protects everyone especially since they all have job from scientists to medical now education in the beginning he wouldn't have saved him since he brought nothing to the table but once he told him "I'm teacher", he saved took him to the safe location now If one gets out of place then the whole system he has build will begin to crush down since they now want to leave and go somewhere else but where though since those things are out there they would rather be there and not say nothing even though they know what will happen he's still scared since what he has seen but things will get out of hand and he would like to leave since he doesn't want to be there no more along with other characters trying to help him escape but might injured in the future.
Something ain't right as soon as he got there both of them stopped talking and left if my theory is correct then he would want to leave instead of being with him because he's tired of it
