I know I talk about in the case of purly and Markboy Soda wouldn't like pony taste in men. But I don't think either of them could come close to how much soda would despise rodeo, randyxpony.
He knows who Randy is and what he's done. Randy was at the trial and he confessed. Not only that but I'm sure any if the gang would recognize that blue mustang. The same one that pulled up on Johnny. And the fact Randy was Bob's BEST FRIEND.
Soda would be fuming if pony brought Randy home. I see Darry not liking it either but he would try to keep calm because he promised to not fight with pony so much. But Soda? Oh much God soda looks like he wants Randy's head to be separated from his body slowly. Obviously Randy would notice it and it would be very awkward.
This would also be the only ship I can see soda never fully accepting. When it comes to purly in markboy Soda is gonna get over it at some point. Even if they keep a civil fued. But rodeo? Oh hell no. Till the say soda dies, even if he's got dementia and can't recognize his own kids. He's gonna see a picture of pony and Randy or here about them and get all pissy.
And trust, he's gonna be throwing shade. He doesnt care if it's their wedding day he'll be the kindest best bug brother but as soon as he looks at his brother in law he just glares.
And if pony takes the Anderson name sodas sobbing and bawling his eyes out about horrible connections but if Randy takes the Curtis name soda says he has no right and aint his family.
He is not letting this go. This is his hill he will die on.
