Gilbert × Alois (two married men in secret fishing relationship)
Not for me I'm afraid. I cannot see Alois with anyone other than his faceless wife. I can imagine many polyamorous relationships for many of the characters in this game, but Alois is 100% monogamous in my mind.
I might have controversial opinions on the "Faerghus Four." Mostly that it doesn't exist, and at worst, it exists to exclude Dedue.
Yes, Dimitri, Ingrid, Sylvain, and Felix grew up together, but that was as children. While that history is significant to their relationships, it ignores everything after. With the tragedy of Duscur, Dimitri and Dedue became inseparable while Felix was sickened by them, Ingrid couldn't overlook Dedue's connection to the tragedy, and Sylvain's apathy grew.
Past the age of ~15, you can't ignore how Dedue and the tragedy affects their relationships. I don't see just the four of them as a friend group, especially not without him because he's so important to Dimitri and the themes of Faerghus.
Gustave (Gilbert) is an unpopular character, I know. But, honestly... I don't care much... I don't have to like a character to enjoy how much he adds to the story and to the other (more loveable) characters' development. Which is why he has such an important role in my fic.
I was re-reading the Dedue - Gilbert support line because of something unrelated and, hm, I find it interesting how people often use their C support to dunk on Gilbert when the reason Dedue gets so incensed about Gilbert's role as a knight and how his regrets have made him choose exile is because he admires what he knows about Gustave from Dimitri's stories ??
And it is mentionned at the beginning of the chain that he has met the man before he left for the Church too (and that he actually looked worse when they met in Fhirdiad, which was probably soon after the Tragedy overall, and now I am wondering if Gilbert was present when Dimitri saved Dedue that day but that's idle thinking)
(also shout out to Gilbert smiling when mentioning how much Dedue has grown idk I t)
And then, in their B support...
... :)
There's something really neat about Dedue specifically mentioning that he also needs Gilbert being part of this war / part of the people here with them, and that he still relies on him (and how Gilbert answers back)
Honestly with all the BS Dedue has faced in Farghus (and he doesn't hold his tongue about it frankly), it makes me think that Gustave was probably a person he thought Dimitri and he could rely on - which frankly would explain how strongly he reacts to the fact that Gustave left. They didn't meet much, they both say, but it makes me feel that at least those few meetings were positive, despite how exhausted and haggard Gustave was. In addition to Dimitri's stories about Gustave, it built a specific picture in mind for Dedue - one he held in high enough regard that he modeled his behaviour toward Dimitri from his understanding of Gustave ?
It's not just for Dimitri that Dedue is angered about Gustave's leaving. He says it explicitely about Dimitri, that Dimitri needed Gustave, but it's not just for Dimitri that he's angered.
IDK
There's something kind of neat about this relation. A lot more than what people usually talk about. It's both distant model of chivalry (and don't forget that Gustave was the one who saved Dimitri and brought him back to Fhirdiad - something I think Dedue would always think about) and this. idk how to say it. But I think they both get to understand / see more about the other and their respective place as knights that they don't really get to have be seen or understood by others ? That in a way they share an understanding of what their duty means to them.
(but now I kind of want to see Dedue cooking some fish Gilbert brings him. Maybe I should do that.)
