Harry was terrified he thought he was going to have a heart attack, he was sent to St Mungo's.
After many hours.
Harry woke up and saw Mrs Weasley
Mrs Weasley: Don't worry Harry, it wasn't a heart attack.
Harry: Then what was it?
Healer: It was a chest monster.
Harry: What the-?
Healer: Harry drink this for two weeks, you will be staying here for.
It was a huge potion.
Harry thought what was a chest monster? He thought of Hagrid he was a bit mad with creatures he remembered the Blast-Ended Skrewts in his fourth year. But he wasn't doing Care of Magical Creatures now. But even though he gave up Care of Magical Creatures, Hagrid understood and he would never do anything like that to him, injuring him or attempting to murder him.
