The only evidence I know of for Ike being a homo is that he doesn't thirst for box to smash on the regular and broadcast it constantly, aka not a real reason, but primarily it's because of Soren. Who absolutely acts like a catty homo so often that I wonder if the twink's meant to be a gay or just so asocial that he finds any intrusion into his bond to be a reason to act like he has severe aspergers, besides that his parents didn't love him.
His reaction to seeing cats interacting with Ike in an irreverant way after all is to immediately call them slurs, making it seem like he's threatened by their presence.
Which, I mean-
Like c'mon, if you don't like her abrasive personality then whatever, that's your preference, but, fellas, do I really have to do a "hear me out" on her? There's no shame to be had. She has, as mentioned before. Acrual chemistry and relationship growth with Ike, and they share an interest in one another, the kind of mutual desire in one another that ensures at some point Priam's gonna have a mark stamped somewhere on his body. You only get one A Support in Fire Emblem and Soren's right to feel threatened.
...When it comes to looks and personality. Gameplay utility? She's non royalty Laguz, so rest in peace for being an endgame pick.
Speaking of half breeds and making them, I remember really liking Path of Radiance's world building and plot, though when I actually go back over it the most development is actually in the supports and base dialogue. Moving the support convos to a place they can actually have variation and aren't sharing space with a fucking battlefield was the most important decision PoR ever made, and the depths these convos went to made me incredibly angry both back in the day and now what Radiant Dawn did to supports. You don't get the two most racist women in the game shut in a room explaining their worldviews in RD, you don't get the explanation of how Laguz were once at the top in a society based on strength and how they see their present political situation as a result of deception. You don't get the tragic conclusion of laguz-beorc relationships based off of mutual superstitions (I don't remember if Laguz actually lose their powers if they breed with Beorc but it would be a serious show of devotion if they did). It all lands ass first and it's really a shame considering all the effort that came before.
As a side note, a detail that seems meaningless and strange, that "human" is the Laguz term of disparagement for Beorc, makes much more sense when you know the history of the setting. Thoererically speaking, "human" as a term in such a case would have come about first, and when Beorc reclaimed it, and over time lost context for its meaning, they called Laguz "sub-human" in their claim for supremacy.
Which adds another layer of why it pisses them off so much. Not only being inferior, but it's like if you call somebody nigger and they turn around and call you, without an ounce of sarcasm, a quadruple nigger.
