I've been reading a lot of resurrection webcomics lately, but I think what makes this one sadder/sting the most is the fact that she's was able to come back but her son wasn't and now she'll live with that memory for the rest of her life...
Like yeah, there's been some other webcomics where they lost kids but those are always while they were still pregnant, so the child never had a face to them and weren't alive long enough to have a personality.
It's gotta suck to get to know a child for some years then suddenly they're not there anymore and even if she does manage to have another child and even if they come out the same, they'll still never be the exact same and will probably feel a little off
well, if the writer goes that deep into it, I could just be overthinking lol
I also just kinda hope she gets another chance, too. Her son was too adorable to be gone for good :c
