The thought behind the stitches

Exploration Stage: Hall of Departure
From: Juliette
Description: It breaks my heart that Alex is going with the Lady with the Smile. The detective told me...that Alex is collecting mementos of us so he can take them with him to the next world. So I brought a special keychain, but in my heightened emotional state, I forgot where I put it. Can you help me find it?
Completed: I'm glad you found the keychain! As I was making it, I was reminiscing about the many adventures that Alex and I have been on. We are connected by many happy memories. I really hope he will be happy in the next world. I hope he remembers us...
