Snape made sure that Harry had just the right amount of ingredients for the potion they were making to make it easier for him.
"There you go, Harry. Raise your hand if you need help."
"I'll be careful, Professor," he promised.
Not half hour later, Harry's left arm and both legs started to shake with clonus, causing him to spill a liquid ingredient into his lap. As he felt his pants get wet he wailed, alerting Professor Snape.
"It's okay, Harry. Come with me," Snape lifted him onto his hip and took him into his private chambers, alerting Draco to come down to the dungeons at once.
Draco was there in five minutes with another outfit for Harry to wear.
"Sorry, sorry, sorry!" Harry sobbed, laying on the end of the bed in the room as Draco dressed him.
"Not your fault, Sweetheart. Now, I need you to calm down, your clonus is kicking in again."
After Harry was dressed again, Draco took him into his arms and sat down on the bed, shushing him as Professor Snape looked on.
"Harry," finally, Professor Snape knelt in front of the boy, "It's okay. We can wash your clothes tonight."
Harry shook his head, unable to speak through his tears. He exchanged arms, as Professor Snape was Draco's godfather and he knew him before school.
"Uncle Severus..." Harry wrapped his arms around his professor's neck.
"Yes, Honey?"
"Are you mad at me?" the emerald eyes looked up at him, pleading.
"I am not, Harry. It was only an accident."
"Okay..."
"Do you want to try again or are you done for today?"
Harry shook his head, "'m done."
"That's fine. I'm going to let Draco take you upstairs to rest, all right?"
"'kay. I love you, Uncle Severus," with a last hug and a yawn, a nearly limp Harry was taken into Draco's arms.
With one last goodbye to his godfather, Draco was out of the room and on his way up the stairs to Gryffindor Tower.
