Lisa had waved her hand at the apology mentioning something about Su not having to worry about any of it. Though she appreciated the effort it was a bit forced and the Ravenclaw really didn't want an apology if it wasn't meant. Not that she suspected Su didn't mean it. It was, after all, a feat to get the girl to admit that she was wrong. Which...kind of made the entire thing unimportant now that it had been offered.
She was a bit surprised when Su stood and she immediately sat up in her chair giving the other girl her full attention. The fact that Lisa wasn't exactly...involved in the current political dramas seemed to make her a bit immune to the situation at hand. Course, it wasn't until that very moment did she put two and two together. Su was quite obviously 'off' because of what was going on. Believe it or not Lisa had a bit of a hard time thinking of Su as a muggleborn. She didn't play dumb like the rest of them.
Suddenly less cheeky the seventh year clenched her jaw and adverted her glance to the floor. "I'm not going to lie, Su - I don't know what you're going through. I mean I can imagine...but it's not the same. I, for one, am glad your safe here. And I'll do anything I can to help you get through all of this... I just- You need to tell me what you want me to do."
