as long as you dont summon some lovecraftian monsters like the Arthur prototype fic, everything will be fine, it was a major turn off on that fic, i mean, dude has a bunch of beasts and foreigner servants from fate to make into the bad guys, and he had to get lovecraftian stuff and make his story even more complicated, the last plot he had before going into hiatus was about searching for class cards or "wild" servants or demi-servants, he just needed to have a foreigner merge with the whale, not THAT, aaaah, well, anyway, your chapter was good.
So is Subaru getting Ram? She’d keep him grounded in reality. Maybe make Subaru sign a marriage agreement with Petra without knowing what it is and then make her bring it up in the epilogue of the story when he’s married to Ram and Petra’s legal. I just found the idea funny as Ram would make fun of Subaru for everything he’s ever done in life. Maybe you could summon Subaru’s parents using Beatrice to give him some closure as it’s unlikely he will take the trials now he doesn’t have return by death. (Everything said here is literally just my first thoughts after the chapter pay it no mind if it annoys you) Nice chapter!
