To be completed when I have free time. Even though it's only just the rough start of one, if you've talked to Remus, let me know so I can add to the list.
Marauders:
James Potter: Ah, James, his favourite little awkward turtle. It's beyond him really that James actually got together with Lily and became Head Boy but he really does love him although he mocks him to hell and back because that's what good best friends do. He thinks it's hilarious that James is so scared of Bellatrix and Narcissa that he's in hiding and changing his name and that his wibbling is really very pathetic. He managed to convince child James that he was under a turtle curse.
Lily Evans: The sane one. Remus loves Lily to bits because they were the top of class together and prior to his break up with Sirius, they could complain about their mental boyfriends together. He finds Lily the easiest to confide in and he loves that he can be silly and have a good laugh with her. He's especially grateful to her for helping him out during genderswap week.
Sirius Black: The one that frolicks, never prances. Remus and Sirius had been a couple prior to entering the house and things seemed to be going well until Remus started to realise that he was falling out of love with Sirius and decided to end things instead of drawing it out. He still cares about him a great deal but he feels awkward and nervous around him and he doesn't know what to say or do and he's not completely sure that they're still friends.
Roommates:
Yamamoto Takeshi: Remus doesn't know Yamamoto all that well because he's off with Gokudera [aka the grumpy one] but he does like that Yamamoto seems friendly and easy to get along with. He likes that he has at least one roommate who is generally all smiles
Saber: Remus doesn't know Saber too well but he did look after her when she was a little girl. She confused him then with all the talk of Sir Ector and the fact that she was dressed up as a lion. He also thinks she's ever-so-slightly mental.
Gregory House: Remus loves to wind up House by being young, charming, witty and a complete pain in the arse, making fun of House being old and unable to catch him if he tries to do something on account of Remus being able to run. A lot of this started the week Remus was turned into a child where he apparently chewed House's cane although Remus has no memory of this week. He enjoys being in a room with him because it makes it easier to spend his time annoying him.
Canon-mates:
Bellatrix Black: Naturally, because she's Bellatrix and a Slytherin, he doesn't trust her in the slightest. He did, however, see another side to her when Sirius was bitten by a zombie but he still doesn't trust her at al..
Narcissa Black:
Andromeda Black:
Nymphadora Tonks:
Friends:
Hanatarou Yamada: Being the nice Marauder and an ex-prefect, Remus feels like he should look out for someone like Hana who might get bullied in the house seeing as he's small and nervous. He hates it when Hana says he's useless and so on and feels like an older brother to the boy and he's determined to make him get some self-confidence at some point.
Drizzt: Drizzt and Remus first met during the kid week but sadly they don't remember it at all. He likes Drizzt, even if he's a little confusing and very different from anyone Remus has met but he's not one to judge on all this seeing as he's a werewolf. He liked his cat Guenhwyvar.
Enemies:
Church: Remus hates Church even if he does find him good looking and that annoys the hell out of him. He likes to annoy him because it's easy to do. He still doesn't know what an emo is after Church called him one.
Not quite sure what category they go in yet:
Gin: Gin was his history teacher for the week and Remus was still in a bad mood over his classes and breaking up with Sirius so he was a snarky git. He's willing to give him a second chance at some point later although he wants to know what the deal with that lollipop is.
Ziva David: Remus likes Ziva even if he finds her a little confusing and he'd like to get to know her a little better although sometimes he really has no clue what she's talking about when she gets some of her sayings a little confused.
Castiel: He likes Castiel and finds him interesting and possibly another person he could confide in because he gets the feeling he wouldn't tell anyone else what he said. After Castiel broke up with Tonks he was angry but he's determined to be civil and he's also in the same boat with being the one to suddenly end a relationship and he knows that what two other people get up to is really none of his business. He'd like to talk to Castiel and ask how he is but he has no clue how to go about it.
