In the demo, it's possible to romance both Thaletas and Kyra. I pick up some wine at one point while exploring, and when I next chat to Kyra, an extra dialogue options comes up with a heart next to it if I want to gift it to her. Romances are dalliances in Odyssey—it's not like you can go full Fable and have three husbands. "You go from an island or a new place in the world, and you'll romance a character there, but it's not like 'I found the love of my world and I'm keeping that character'," says Dumont. "It's much more casual, a spur-of-the-moment type of romance."
Kyra is probably the most interesting supporting character in the demo—she's been fighting Podarkes and his forces on Delos for some time, and hangs out in an underground hideout with the rest of her allies. I don't want to spoil what happens during this quest in case you want to see it yourself, but eventually you do clear out Podarkes' forces, which is kind of obvious. I killed him at a point that actually cut off several other missions of the game, partly because I took him on several levels above where I was supposed to. The quest line then ends in a party, where Kyra and Thaletas attend.
What you say to them at this point can apparently determine which of them lives and dies, and there are even what's described to me as 'wild card' scenarios, where a seemingly unrelated decision of the player's affects the outcome. That happened during my demo. I saved a prisoner, and it had deadly consequences later on. And in the aftermath, I had to decide whether the prisoner lived or died. These actually feel like interesting choices.
