When you run in the maze:

Thomas:
Thomas made checked in you every once in a while. You'd some how meet in these places that connect the maze.

Newt:
He was extremely worried about you in the maze. He waited by the door every morning and every night.

Gally:
Gally was very worried, but accepted it. He made you a small piece of wood with a message carved into it.

Minho:
He would have you run with him. Sometimes using the alone time to kiss.
