It was bitter sweet when Elias gave himself to the soul catcher. and I felt really bad for Laia because she was so heart broken.
I did think it was nice that when Elias felt lonely Mauth was said "you are not alone".
I thought it was funny to think that Elias and Mauth are part of a "group project" and Elias is the kid who does not do anything.
I also don't think all is lost for Elias and Laia to be together. All Elias has to do is pass the job onto someone else.
