Can you comment more please "picked the boy up and settled him on his hip and the crying stopped in seconds." "by Adam's side and held the fabric of his jeans between forefinger and thumb," "One of you should now be in touch with the authorities,"

Since both of the other quotes have been addressed, we will look at the quote in which Mark is standing by Adam's side holding "the fabric of his jeans between forefinger and thumb."

Mark's gesture in this scene is telling.The fact that he is holding onto Adam illustrates a sense of safety.... for some reason he trusts Adam enough to stay by his side.... Adam makes him feel protected, and Mark does not see him as a threat.
