We’re largely drawing here off other people’s reports, Harry’s memory of their death, and one brief scene from Snape’s pensieve. but James latches on to people— Lily (who he dies for), Sirius (who he takes in, and changes), Remus (who he becomes an Animagus for).
James is also framed as their leader (see: Gryff secondary). You could read him as a lot of things, because we see so little of him, but we think the simplest explanation for him is a Slytherin primary. When he goes in to stop Snape from getting chomped by teenaged Lupin after Sirius almost lethally pranked him, it’s framed like James was doing it for *Remus* not for Snape (the way a Hufflepuff might), or because it was wrong (the way an idealist might). It was going to hurt his Lupin; so he stepped in
Lily Evans is a Gryffindor/Gryffindor. Her secondary, shouting at that bully Potter, charging with all that red hair flying, is fairly obvious. Her primary, though, we get from the two main interactions we’re given about her: with Snape and with James. She befriends Severus and stays friends with him even as he repeatedly shuns her sister, joins up with nasty people, and calls her slurs. She stays his friend, forgiving, up until she decides he will not change, and then she leaves him with apparently very few qualms. This does not quite follow with the intense personal loyalties of a Slytherin, or the general loyalties of a Hufflepuff. A Hufflepuff will stay your friend and continue valuing you despite your errors and wrongs; they are actually less good at forgiving than (young, uninjured) Gryffindors, who tend to assume people will and can come to their senses and change their minds for the better.
We see this tendency, too, with James— we don’t see it, but we know that Lily went from hating the bully to remarrying the reformed young man. When James changed, she bought it. When James grew up, she believed it and she fell in love. Lily’s valuing of the quality of one’s character and her tendency to have faith and believe people will change for the better (until they’ve stepped on her as often as Snape did) is evidence for a very warm Gryffindor.
Severus Snape is a Slytherin/Ravenclaw with a solid Slytherin secondary model. His focus on and obsession with Lily is a very unhealthy and nonconsensual example of the Slytherin primary’s loyalty. Through loss, through death, through different sides of a war— when it came down to Lily’s life vs. the Dark Lord’s wrath, the cause, everything, Snape’s priorities were immediately and obviously the safety of Lily Evans. He is not fighting for ideals or reasons; just for Lily. And it feels slimy and stalkerish the way Narcissa’s love for Draco feels warm and powerful.
Snape looks a bit like a (rather unflattering example of a) Slytherin secondary in that he is false, that he lives in a twisted persona and not a self— but he’s actually a Ravenclaw secondary who’s had to learn really well how to be a Slytherin. He does not react or improvise with much skill or enjoyment. He is deliberate, studied, and planned.
You could definitely argue a “burned” secondary for him—he seems to err towards Ravenclaw, with a bunch of learned Slytherin tacked on, but he also seems to have decided that methods are immaterial and all equally a bit useless. He’s despairing in a lot of ways. His primary has not burned in the least — he holds to and is driven strongly by the loyalties and priorities of his Slytherin primary. But he’s lost faith in methods, in use, in… a lot of things.
Peter Pettigrew is a Hufflepuff secondary. Hufflepuff secondaries don’t have to be the community builders— they can also just thrive in or feed off of built communities. Peter draws a lot of his use and strength from tying himself in with powerful people— with with the marauders, and then with the death eaters. When he cuts off his connections is when he becomes useless. His strength are almost always the strengths of the people around him.
Peter’s not a Slytherin primary—his personal loyalties have little to no effect on his actions or his guilt. He’s not a Hufflepuff, either, which leaves the two idealist houses. We try to take canon into consideration when sorting within HP verse— and, we emphatically refuse to sort the single and sole malevolent Gryffindor into any other house. Gryffindor gets to keep its villains, too— so, that makes Peter a Gryffindor/Hufflepuff.
Peter has an intuitive sense of right and wrong that allows him to move through his betrayals and skittering with a sense of justification. He does not feel guilty—listen to him plead and explain in the shrieking shack. He has given himself excuses and he believes them with the wholehearted certainty of a particularly selfish Gryffindor primary.
Sirius is a Gryff/Gryff, just like Lily— James may have a type. Sirius’s vehement, “You should have died rather than betray your friends!” in PoA is a statement of such strident, destructive loyalty that we were tempted towards Slytherin Primary, as with James. However, JKR’s extracanonical discussion of Sirius convinced us of Gryffindor. This was still about right and wrong, not loyalty. Sirius has a Slytherin model, probably, but deep down the boy’s all Gryffindor.
JKR: I think the question really is do you, as readers, believe that Sirius would have died? Because Sirius is saying that. […]
Sirius would have done it. He, with all his faults and flaws, he has this profound sense of honor, ultimately, and he would rather have died honorably, as he would see it, than live with the dishonor and shame of knowing that he sent those three people to their deaths, those three people that he loved beyond any others, because like Harry he is a displaced person without family.

Lupin is a Stripped Gryffindor— he’s an idealist, and he has a sort of careful, built idealism that hints at Ravenclaw. However, he feels bad about it; or empty. He wants to be intuitive and brave, but his life has been such that his surety in his self and his goodness is shaken. He has to build it, when he wants to just be it. But this is a boy whose very body fights him, and the way he has dealt with that is to Fall and to build himself a system outside himself.
Lupin also has a strong degree of Hufflepuff — he values kindness. He pays attention to the kids in his class, not just what they learn but how they are. He is the one to provide chocolate after dementors, to the kids huddled in his train car. It’s a Hufflepuff that feels slightly detached from him, in some ways — it’s something he’s grown into much more in his Bk. 3 and later appearances, than it seems in the few Marauders era flashbacks and stories we get. In the flashbacks and stories, he is a rule follower, and a tagalong, a good friend — but not the specific kindnesses of Lupin we see in Harry’s childhood experiences.
We think he’s a Hufflepuff Secondary, but that this is a secondary that he has lost faith in, like he has lost faith in his Gryffindor primary. Remus is hurting and he feels destructive, polluted, and wrong. He cannot trust those kindnesses to come from his hands; he cannot trust that he should be building communities and tying himself to people and groups, which is the strength and joy of a Puff Secondary, because of that internal pollution and risk. We see it, too, in his reaction to Tonks’s pregnancy. Remus wants connection, fears it, and flees. His school years were years of him fleeing, quietly, blocking out the kindnesses and connection of his Puff and clinging desperately to the effort, integrity, and rule-orientation it can also embody.
Snape and Lupin seem to both have burned secondaries — they’ve lost their faith in the efficacy of their methods, or the worth of their own hands to use them. In safer moments, Lupin has the kindnesses and emotional investment of a Hufflepuff Secondary and Snape has the deliberate good sense of a Ravenclaw Secondary.
With absolutely zero details about Dragon Age 4 (aside from the teaser image of a burning lupine chess piece and the camera zooming in on Tevinter), I’ve already started crafting my DA4 protagonist. I’d love any information about the game, and soon.
