DRAMA DRAMA DUCK
ROZE THOMAS: Roze is someone that Severus has a hate/not hate relationship with. While he doesn't want to admit appreciating her offers of friendship he despises her for reminding him a little of Lily Evans. Still, at this point she is his one sort of friend and keeper of some of his darkest secrets.
DENZEL CROCKER: Crocker ticks Severus off. The man clearly has issues and yet has a wand that he knows how to use. Additionally, Crocker worries Snape because of his friendship with Gellert Grindelwald and how both men seem to share the dream of exposing the magic world to the Muggle world. In general, though, Snape views Crocker with great disdain but still someone not to be underestimated.
JAMES POTTER: James is the biggest thorn in Snape's side and the brat knows it. In Snape's opinion, James is an obnoxious blowhard who might be dangerous if he had half a brain cell. Snape finds the man's level of self-centered-ness to rival his own and despises his inability to see past his own tiny view of the world.
GELLERT GRINDELWALD: Gellert is a danger in Snape's eyes - not only to the network and the worlds connected to it but also to himself. Snape damn well knows why Dumbledore refuses to give him the Defence Against the Dark Arts position at Hogwarts and it is for the same reason that talking too long to Gellert is - the Dark Arts are seductive temptresses to Snape. While he knows he has to keep an eye on Gellert and try to figure out what he is up to (as he is a member of the Order of the Phoenix and loyal to Dumbledore to an almost unbelievable degree) he feels the dangerous pull of a part of himself he tries to keep reigned in per his promise to Dumbledore so many years prior. Gellert is perhaps more of a threat to Snape's humanity than he is to the network at the moment and that genuinely frightens Snape - even if he won't admit it to himself.
EMILY CHARLTON: A woman Severus hates so much that it might be love. She's unpleasant, self-absorbed, catty - an all around bitch. He enjoys antagonizing her as she usually provides him with a lovely fight. Perhaps they should just get a room because it would be the most glorious hate!sex ever.
BELLATRIX LESTRANGE: A one time friend, Bellatrix now serves as Severus's link to a future that others have told him about - a future in which he kills Albus Dumbledore. Quick to reproach her for her outbursts, she is also one of his favorite people to antagonize. He views her as a batshit crazy Pure Blood whose family tree could have done with a little less inbreeding.
