To him, Laurel and any of the other "weaker" vampire families probably aren't worth remembering for him. Well Vlad is evil, so he's probably jealous that she's killed more people than he has in a while.
Yvette is torturing herself over what she did and dealing with Vlad messing with her. She was completely miserable there. Yeah, it's hard to know who to feel sorry for when the last victim is morally questionable himself.
Emmanuel was really unlucky, especially since he's Caleb's kid and Vlad hated his father so much. Yvette did what she could, but she couldn't be there for him all the time.
And having Blaze torment him while being locked in a tower isn't an ideal way to grow up.
Yvette's siblings love her, and they've seen first hand of course what Laurel's capable of, especially Constance who saw the whole incident with Bernard causing Dominic to drown. Which, I feel like Bernard possibly should've been punished too, but he also didn't know what he was doing. In my mind he probably lives in his own little world trying to forget what happened. If he was around when Grim did all the reaping, he might not have made it. Yvette is genuinely appalled by what she did, as opposed to being in denial, and it was less accidental? Anyway it she didn't really have much of a choice, which I think makes her a bit more sympathetic. Yes, they definitely had fun following Laurel around and messing with her!
Blaze was just too impatient and too much like Laurel for his own good. He got really power hungry and full of himself, especially since he was able to cheat death once. I think Grim wasn't too happy he was back because well it was his time earlier, and Blaze coming back caused a lot of unnecessary chaos. Yes, everyone who was especially awful got what was coming to them. I felt like it was only right for Blaze to die along with Laurel and Vlad because he did a lot of awful things as well.
Eh, yeah Grim wants kids, and he "gives them away" a little too easily. There's lots of ways to get a reaper child, and making a deal with him is one of them, though usually it doesn't involve as many kids as Yvette has to have! I think Grim also felt a bit sorry for her but knew he couldn't let her off the hook for being responsible for Caleb and Lilith's deaths completely. He knows a lot, so he also probably knew that was what Yvette needed to start to heal.
I'm kind of sad it's over, even though I don't enjoy killing sims. I'm definitely going to keep playing with all the kids though!
