On May 5th, 2016, it was revealed that Harry Potter had lost his Parseltongue ability. Parseltongue is the magical ability to communicate with snakes, and it is a rare ability that is usually only found in descendants of Salazar Slytherin. Harry Potter had this ability, and was able to speak to snakes since he was a child.
However, when Voldemort’s soul was destroyed, Harry discovered that he was no longer a Parselmouth. This was an unexpected bonus of Voldemort’s demise, as it meant that Harry no longer had to worry about his ability to communicate with snakes.
It is unclear why Harry lost his Parseltongue ability when Voldemort’s soul was destroyed. Some speculate that it was because the part of Voldemort’s soul that was inside Harry was what gave him the ability to speak Parseltongue. Others believe that it was because Voldemort’s death meant that Harry was no longer connected to the magical world in the same way, and so he lost his ability to communicate with snakes.
Whatever the reason, Harry Potter no longer has the ability to speak Parseltongue. This is a great relief to Harry, as it means he no longer has to worry about his ability to communicate with snakes. It also means that he is no longer connected to Voldemort in any way, which is a great relief to Harry and his friends.
