Wilson looked at the two. He closed his eyes and waved his hand. He uses the Muffliato curse so only Amelia and Arthur could hear him. He stood up. ''You two seem to be pretty confused about my statement, both of you. And do not worry, no one can hear us. What I said, I meant it.'', he said as he stood between their two desks. He positioned himself diagonally and put his left hand on Arthur's and his right hand on Amelia's shoulder, ''connecting'' them. ''Arthur, my dear pupil, she is perfect for you, despite your bewildered look. She is extremely beautiful, intelligent and you are you, she would fit you perfectly. And you, Miss Lyons... he is, well I can't say he is beautiful, that is up to you but... he is not ugly and he is intelligent. You are... well, you are you. Although you dislike him because you think he is pompous, and yes, it is quite obvious, even to him, but he is not like that, he is just a know-it-all. You two, however you may disagree, although I do not know his opinion, never spoke to him about that, would fit each other perfectly.'', he said, tapping them on their shoulders.
He returned to his desk. ''Mark my words, both of you! Arthur, m'boy, as McCoy likes to say, do change a little, and Miss Lyons, do be more... softer... softer could be a fitting word. But, I am sure you all know what I am trying to say.'', he added with a smile and removed the spell.
Arthur looked at Wilson, smirking a little in disbelief and then turned to Amelia to see her reaction.
(Sorry if you find it to invasive, I will deleted the post... but I think it is a nice touch. But, you decide)
