Well, at least that leading to a non-standard game over when Helanya killed Rowan would still avoid complicating the plot

...
But I was thinking of it more like "I care deeply about you, and can't bear to have your death on my conscience. Please, please don't throw your life away by trying to escape while you're in this condition.". Followed by using her feelings for him, and the curse, to progress down the love route without having had to explicitly say that he loves her instead of Alexia. Since he still cares deeply for her, it shouldn't require any change to the rest of the events - especially when one considers how those emotions would probably grow more intense once they're actually together.
It still seems rather skeevy to me, but less so than saying he loves a woman he hasn't seen in years instead of the wife that he's loved since being a teenager.
(Though for the record, I've always seen Rowan having sex with Helayna as more of a "necessary action to keep her coherent", rather than a bonus. I mean, so long as he's sleeping with her, he can't even share his room with his wife; that doesn't seem a good trade to me.)
Ah, and just to reiterate, I
do see this as being a personal issue surrounding the use of the term "love" in the event, rather than as a legitimate game issue, so I really won't have any complaints with the event staying as-is. It'd be selfish to expect that game to cater to me personally when there's so much work to be done.
