Actually yeah thinking about season 2 now if we keep the Gertrude/Jon/Elias divorced polycule. Jon maybe knowing intellectually his mum is dead, because there was a lot of blood. Though part of him hopes she was just faking it, thought that means she abandoned him instead, either way not good.
Then he gets confirmation that his mother was murdered, and probably not by a monster. Jon being so certain he’s next and too paranoid to even get to mourn properly. Nobody but Elias knows what their relationship actually was so no one else gets that that was his mum. Going to Elias to cry and not knowing that the person he’s crying to is the one who did this to him.
When Leitner says it was probably Elias, Jon defending him because no that’s his dad he wouldn’t.
During the ‘confrontation’ when Elias admits it? Admits that he took away Jon’s mum, and his excuse was she was going to destroy the Archives? Jon not even able to do anything because part of him, the monstery part is horrified at the thought of his Archives being destroyed. Jon wanting to go to Elias for comfort but he can’t because wouldn’t that be wrong?
Jon locking himself in his office to cry, and mourn his mum.
