Hmmm, not particularly headcanons (I don't have many for SFTH stuff to my surprise) - but I absolutely love DerLucht's interpretation of them on their fic Made of Steel on AO3 (which is an amazing fic btw, I absolutely loved it) where she is just magic and can do stuff like change the weather. Margaery should do more actual magic, I want to see her do crazy things with magic no explanation and brush them off like it was nothing, I want to know what she's been doing all those 2000 years, how far back does she really know Titch's family and why??? I just need more content about her she's so fun
For James and Titch I really only have general story ideas, like I really wanted to write something about the first time James called Titch his brother - or vice versa - but I couldn't come up with any concrete plots.
Like it could be in a fit of emotions, maybe they're younger (cause who knows when Titch was adopted) and Titch gets lost and James has to look for him and it just happens, like he just finds himself calling for his brother. Maybe it's just natural and he doesn't even notice it (maybe happening out of panic or something), or maybe it surprises him (though I think I prefer it just being natural). I imagine Titch being really surprised by this, maybe struggling to find his place in the family and wondering if he belong (Another version of emotions could perhaps be anger which could be interesting)
I could also see it being casual, maybe just like a "good morning, brother" which surprises Titch
Or, I had a vague idea of combining all three of them and - again, probably when they're younger, but I suppose it could also work for when they're older - maybe on some major holiday (I was thinking Christmas since it just passed and it was on my mind) Titch gets a bad injury that needs tending urgently (or James, I suppose, but I just like injured Titch, I guess, lol). For plot convenience maybe they live in a really small town and any doctors/hospitals are closed (and if they're younger their father isn't home, I couldn't decide why that would be other than an issue with the farm or electricity or something) and so instead they go to Margaery who helps them out. I like the interpretation that she's got a soft spot for both of the brothers even despite their chaos and all of the things they bother her about
I just love scenarios that show how much Titch and James care about each other - but particularly when James shows that he cares about Titch because I feel like I see less of that
Woah that was a lot more than I expected
Got the sudden urge to post so here we are
Thinking about The Unrelenting Aubergine again too much- as much as I love Ditch (they consume so much of my brain) I would love to see more stuff about James - especially his dynamic with Titch, but maybe also his dynamic with Margaery
And just more stuff about Margaery in general - I love her, she is amazing. I want more fics just about her (I’d write them but I don’t know what I’d write 😭 I’d write the James and Titch stuff too, and I have some ideas, but not how I’d write them and they’re just general concepts. I’d love to hear more, too)
