Missed Tattles

So I’ve played the OG game many times over, but playing the remake is the first time I plan to fully 100% every thing. I know in the original game you could get missed tattles via Frankly’s trash bin, but I’m missing a few I can’t seem to find.

Currently I am at End Game chapter 8, and I do mean END GAME. I went all the way to the final door and then whipped back around to go do all the troubles, collect the badges, etc.

The problem is that I accidentally killed Doopliss 2 and Marylin 2 before I could tattle them and their pages aren’t in Frankly’s Bin. Also, I had to look up the Goomboard, but when I went to fight the Battle Master, I suddenly couldn’t find him ANYWHERE he used to be.

Did I screw myself over somehow? I know there’s an after game now. Can I find them there?
