There are some people that think that Draco Malfoy might have been turned into a werewolf, but Harry Potter saw Draco go into Borgin and Burkes. As he saw that the shopkeeper and Draco were discussing something, but Harry wasn’t close enough to hear.
However, Harry did see Draco show the shopkeeper something that was on one of his arms. Perhaps to show the shopkeeper who he was dealing with?
Could Harry be right about Draco becoming a death eater?
As really, I can’t imagine even if Draco Malfoy said that his family were friends with Fenrir Greyback that werewolves would bite their victims on the arm. As when Bill Weasley was attacked, he was mauled in the face by Fenrir Greyback.
As in Harry Potter and the Half-Blood Prince Bill was trying to protect the students at Hogwarts.
Then the fact that Bill’s face was mauled makes me question whether Draco really was bitten by a werewolf.
As perhaps Harry’s theory about Draco becoming a death eater is right? As we know that Voldemort places his dark mark on his, followers which are called death eaters, arm.
Then as it turned out Voldemort had set Draco the task of fixing the damaged vanishing cabinet and when he was finally successful other death eaters then arrived through the vanishing cabinet as there was two. As the other vanishing cabinet was at Borgin and Burkes.
Voldemort also wanted Draco to be the one that killed Albus Dumbledore. Although Draco had succeeded in disarming Dumbledore of the Elder Wand Draco didn’t know about the Elder Wand. Or the fact that Albus Dumbledore ended up with it after Albus had defeated Grindelwald and at the time Voldemort didn’t know either and nor did Ollivander the wand maker.
As Voldemort decided to kidnap Olivander in Harry Potter and the Deathly Hallows so that he could question him about wands.
Harry also went to Arthur Weasley and told Arthur that he thinks Draco has become a death eater, but Arthur Weasley told Harry that Voldemort wouldn’t use a kid.
I can also imagine what Harry thought of Arthur Weasley reply as Harry told Arthur who knows what Voldemort would and would not do.
Then Harry tried telling his headmaster and Albus Dumbledore couldn’t or wouldn’t tell Harry yes Harry I know as I told Professor Snape to help Draco.
Then perhaps the reason why Albus reacted that way is because Albus would’ve definitely wanted Harry to focus on what he and Albus were discussing in the private lessons.
Though Albus Dumbledore was aware that Draco has been trying to kill him and when Draco had Albus, up on the tower and the headmaster kept the discussion going for Harry’s benefit maybe? Albus then realize that Draco was taking too long and so the headmaster told Draco that he wasn’t a killer.
Also, Professor Snape did try to help Draco. As Professor Snape told Draco that he had made an unbreakable vow to Draco’s Mum.
I also think that Professor Snape and Albus Dumbledore was aware of what happened to Draco.
As Albus Dumbledore did offer to remove whatever was on Draco’s arm before Professor Snape arrived to save Draco by killing Albus Dumbledore.
As Harry later on discovered in Harry Potter and the Deathly Hallows that his headmaster’s death was planned.
As Professor Snape left a memory for Harry in the headmaster’s office and also Voldemort told Lucius Malfoy that Draco didn’t turn up with the others when he had pressed the dark mark.
So, I suppose because Draco didn’t turn up when Voldemort expected him to, proves to some people that Draco wasn’t a death eater. Though maybe the reason why Draco had decided to not turn up as in the end he decided to defy, Lord Voldemort which is what his, Mother did too when she asked Harry is Draco still alive?
As Harry was able to tell her that Draco was.
