"We were just coming over here to check on him."

They'd probably heard from the workers that I usually came by after hours to check on things.

"He comes back to check on me every few hours. "

"You came back to check the children again the following day?"

Bob was back, and he would no doubt be coming up here to check on him soon.

No one came to the cell to check on them.
