What Exactly Did He Do?

Without paying further heed to him or his words Alaina stepped into her room. Fully expecting to see Aria on the bed with bandages wrapped up on her body as a prophylaxis he must have performed on her when he came in here to help her. 

Either that or she thought Aria would be exactly the way she left her, which would mean he didn't follow thru with his promise; because there was the possibility of only these two scenarios. 

But she was once again surprised to see her friend like that. She slept right where Alaina left her, understandable. 

Only there weren't any bandages wrapped up on any part of her body but neither was she whimpering in agonizing pain anymore. 

Despite there being no change whatsoever, there was a whole new scene. Alaina can not say that he didn't do anything to help her. But then It looked like he didn't do anything and then it looked like he surely did something and that something was big.
