Small issue about the sequence of the story events
It is possible to advance Emma & Felicity's story quite a bit without doing Ashley's quest to search for Ren.
As such, there's a weird break in continuity where you can get the Stoneface reveal before any of the buildup through Ashley's story, and before his name is even mentioned in the story.
I was very confused by Felicity and Emma's story because of this, and only understood what when wrong when I finally got around to advance Ashley's quests and learned about Stoneface properly.
