Wyrmtongue's School Years: A Summary
Dementors. Dementors everywhere. Oh god why! Is this how it normally is? What is this place? (Bear in mind: he's lived with Muggles all his life). On top of that: bullies, escaped murderers, and his first DAtDA professor turns out to be a werewolf.
Yay! There are people here who don't care about the fact that he's in Slytherin! Bullying drops by about 40%! Except oops, now he's gone and learned that they teach the Dark Arts at Durmstrang, and the twelve-year-old Loki is very intrigued. Also... that Potter kid must've hit his head on something, because no way Voldemort is back.
UMBRIDGE. FUCKING DOLORES UMBRIDGE. WHAT THE EVER-LOVING FUCK. And whatever the pink abomination thinks, Loki is inclined to think the opposite. So he believes Harry's story (mostly out of spite), but doesn't join the DA, choosing instead a more subtly subversive route (Snape becomes an excellent resource).
Woo! Snape is teaching DAtDA, and Slughorn is teaching Potions! Finally, what looks like a normal year, with professors he actually likes. Except fuck... Snape's killed Dumbledore and is on the run, and Loki can smell the ensuing shitstorm twenty miles off.
Carrows. Carrows. Carrows. Stay under the radar, don't get hurt. Don't say anything, unless they'll approve. Turn sixteen, get the hell out of dodge. Looks like Voldemort's on the winning side this time, so better join him. And learn now what it feels like to kill. Tell self it's not enjoyable... because it is, but you're not a psychopath. Kill, kill, and betray. Betray a traitor father, betray a cruel monster, and know that whatever happened, you did the right thing. Take pride in wounds, and try to get at least a few hours of sleep each night. Beg for mercy, and lie. Survive at all costs. With skin intact, preferably.
Stay under the radar -- that's all that matters. Don't show anyone the Mark, don't show anyone the scars. Don't wear green except when you have to. Pretend to be a hero (they all saw you kill the Death Eater), but don't pretend too much, or they'll call your bluff. Spend every waking moment not spent in class or with Emma in the dungeons or in the library -- except to eat. Because that's important, but not very. Schoolwork is everything, and life is secondary. Make friends with teachers. Take refuge in Emma.
Study. Schoolwork is everything (almost). Smile kindly, speak when spoken to. Be humble, be courteous, be quiet. DON'T SHARE OPINIONS. Study. Take refuge in Emma -- the only friend you have. This will all be over soon enough. Be the best, but don't let anyone know. Earn house points, but don't let anyone know. Smile quietly to yourself when Slytherin wins the House Cup for the first time in years. Leave Hogwarts with head held high, and scars dutifully covered.
