"Yeah... I'm okay." Theo told the professor when he'd been asked if he was okay. Pushing a smile on to his lips, so that he could try to pull that one off, Theo sat quietly until the lesson began. Truthfully, the Hufflepuff didn't know what the Accio Charm was. Or, he didn't think he'd known until someone had explained that it was the Summoning Charm. Mentally facepalming for not knowing that, Theo listened intently to the professor, nodding along as he understood what was going on.
When they were told to give it a go, Theo took his wand from his pocket and looked over towards the feathers that the professor had asked them to start with. The second year stood up, but stayed at his desk, having a clearer view of the feathers, he moved his wand like the professor had, and said, quite confidently, "Accio." One feather - Theo hadn't been concentrating on just one, and therefore was being too unspecific in his attempt - gave a tremble, but didn't come towards him.
Frowning, Theo did the same thing again, changing nothing. The feather simply trembled again, and the Hufflepuff boy let out a sigh, wondering where he was going wrong.
