he literally said in the interview he didn't want to say who the canon lover was because then people would get the wrong idea about the direction he wanted it to go in. You can literally go to the interview and watch it and see it yourself. Spencer is Dyne's personal canon but he specifically doesn't set one as the definitive because, as he said himself, he wanted to leave that up to the player.

As i was saying, i saw other comments about Spencer's route being canon (Twitter and Patreon) and he confirmed that the route is not just his personal canon but simply the canon, true route of the whole novel. So I will stick to my statement. You can also ask Dyne about it in details on Twitter. But if you're right, it's okay. Spencer will always be my canon (as well as canon of many, many people) no matter what ^^
