When they are injured:

Newt:

You make him rest. He doesn't like that idea, being second in command and all, but you made him. Occasionally kisses keep him there.

Thomas:

You make him sit in bed, since he refused to sleep he might as well sit down. You did your jobs, but stayed with him as much as you could.

Gally:

He is always trying to build things, but you make him stop and rest, much to his protest. Since he refused to stay alone in bed, he followed you throughout the day, sitting on the ground while you worked.

Minho:

He doesn't like missing a run, but had to come to terms with it. He makes you cuddle with him, wanting to keep you close when he felt ill.
