I did not I just read the latest chapter and it seems like everything's going to be okay soon. And now I understand why the new season was necessary. We only got bits and pieces about the grandpa and it was important to show more of him (just my opinion).
I just added the spoiler tag for those who might be reading the previous chapters. Sorry if it was confusing I just wrote what I was feeling after reading this.

Everything is gonna be fine soon And now I know this season was necessary!
