Benjamin followed Ari, but before leaving the room he went to Dia to give her a kiss on the cheek. "Stay safe, we'll see each other in the morning again."
After that, he left the room, after making sure no-one of the staff was in the corridor, and he walked back to his room.
Knowing Dia could walk around made and look after Ray got rid of that worry, and he was certain Dia would be okay. That Josh was probably still around and he seemed to be on their side, for now at least. 

"You're welcome to stay with me," Benjamin said, although after the order of Dia it didn't seem either of them had much to say in the matter, "but I would appreciate it if you'd give me some privacy when I change in my pyjama's."
