should our characters date?

Zeltzin and La Idyn fake dating as part of a psychological tactic against Merry

That should absolutely happen

It would be very funny in part because they are very incompatible

They would be a TERRIBLE couple

Zeltzin just :/ at all of his best lines

I don't think Idyn would fit with anyone in the party very well, honestly

Someone asks what she likes about him and she visibly has to think about what she's going to say for a moment and settles on "...well, he's handsome"

If there were a compatible party member Risken would ensure them wed before the end of the season

But there is not so Risken will make sure that no one succeeds in any rash endeavors

I think in several cases the answer is "probably not, but unfortunately no one can stop them".
