I’m going to make him take anti-venom for around a year before Nagini’s attack so he’ll survive. In the fall after the Battle, he’ll be returning to Hogwarts as a professor. I want to try and rp him as trying to adjust to all of his deepest secrets being exposed when prior he was the most hated man in the Wizarding World. Now, he no longer has that privacy that he enjoyed.
So, he’ll behave differently as he adjusts.
However, if you wish for me to rp him in a different canon, then message me and we can discuss. I’m basically going along with this, though.
