"Focus, Potter," Snape snapped. Harry, of course, gives Professor Snape a glare because he was trying to work on the occlumency as best as he can.
It doesn't help that Harry gets distracted at times.
Or the fact that there's a teacher who keeps yelling at him.
Not fun, being in this office for sure for Harry.
He looks up at Snape because the next thing he hears is important and helpful for him.
"I know this something you can do, but Potter, it's not just about magic, it's about how you survive, control and master your emotions and your mind. You don't want the Dark Lord to get to you."
Harry has a purpose now. He understands for the first time what he needs to do.
For his survival.
