Theodore Nott

You and Theodore have been best friends since you were little. You were both in Slytherin. You were in the library, reading a book. You were alone since the library was empty after a certain time. You saw Theodore arrive. He knew it was your favorite spot and that you stayed there when the library was empty. He walked over to where you were sitting with a smile on his face and a necklace in his hand. The necklace was beautiful.

For a moment you thought it was for you because Theodore gave it to you. You looked at it and said:
—Theo, I-I, it's beautiful—

Theodore didn't let you finish the word and spoke himself:
Theodore: —Do you think Pansy will like it?—

Theodore asked. You handed the necklace back to him with a dejected expression; Theodore noticed, but said nothing, waiting for your answer.
