There were a few things that struck Tonks as odd after Luna spoke. First was the fact that the other Ravenclaw girls played tricks on the poor girl. She seemed nice enough, Luna did, and certainly not deserving of any long-standing ridicule. "I got made fun of at times too. Peeves liked to pick on me so." Because of her clumsiness. Tonks admitted this and then nodded, "That is true. You can't disapparate within the walls.."
But the last part. That was the most surprising part. "But you're Ginny's age--" Oh. Time travel. She frowned then, trying to recall whether timeturners brought a person to another place as well as another time. "I wonder if this is your time or my own. Or neither." Two years. "Things got better? If you're still at Howarts? Or are they the same?"
