nvm, i just read the logs so i figured it out, however, how do I find Cassidy's Journal.
Side note: All paths with Investigating for Cassidy and Cassidy tea time at Saturday Morning dont show up on the disscussion map
You can find Cassidy's journal by talking to Jenny when she's alone in the garden/by the tree. I don't exactly know how to trigger it since these paths involving investigation aren't laid out in the event logs, but I assume it's triggered by starting the investigation. When you talk to Jenny about it, choose to keep the journal.
