Professor Snape is single
Professor Snape is single.
Do you mean DOES? Because the answer to the is no. Professor Snape really never tells Harry, but Harry sees Snape's memories and figures it out. This, of course, is after Snape was killed.
His name is Snape.
No, they work on opposite sides. Bellatrix Lestrange works for Voldemort, Snape works for Dumbledore / for the Order of the Phoenix, that is, for the anti-Voldemort movement.
Hopefully not.
No, why would he be doing that? Plus he is dead.
Well, the books are quite misleading and you don't find out until the near-end but yes ("Sanpe") Snape is on Dumbledore's side
Professor Snape did not take girls to the Yule Ball in the "Harry Potter" series. As the Potions Master at Hogwarts, he was more focused on his duties and had a stern demeanor. The Yule Ball was primarily a social event for students, where they invited each other, rather than for professors. Snape's character is not depicted as participating in such social activities.
He acts like he's a deatheater, but he's really working for the order.
Definitely not. Bellatrix hates Snape and is suspicious of his loyalty to Voldemort. Plus he is a lowly half-blood.
He isn't married but is not single. He has a life long partner that he met at college. (I was gutted when I heard lol)
Snape follows Lord Voldemort because he needs to know what he is up to so he can report to the portrait of Dumbledore, hanging in his office.
