By thedirtyknapkin@lemmy.world's description I know what scene they're talking about. It's not great but it's not as bad as they make out. Basically she ends up traveling for a bit with this really smarmy dude. Think incel used car salesman. He's described as having greasy hair, he's clearly not trustworthy and acts only in his own best interest, and is constantly trying to get into Ciri's pants. But, he's riding this incredible horse the likes of which Ciri has never seen before (and it turns out to in fact be a magical horse) and Ciri is just entranced by this incredible and majestic horse, and smarmy dude can tell, so he makes sure to use the horse to get Ciri to interact with him even though they both know she wants nothing to do with him and only gives him the light of day to see his horse.

Anyways smarmy dude and Ciri end up running from some bandits, smarmy dude is injured but plays down how badly, and basically uses this plus gifting her the horse she's so entranced by to manipulate and guilt her into agreeing to sleep with him (from her perspective it's been made clear how curious but nervous she is about sex, so she's not entirely opposed, but it's also implied up to this point that she's far more into women than men) and then just as she's starting to potentially enjoy the pity sex with the asshole but before either of them can actually get their pants off, he fucking dies!
