This is my analysis... Leena's guardian angel might be Devin himself but he might have gone to trauma sort of after witnessing Leena's state... When it's a severe trauma, patient tend to forget the memories of that particular event or even the person who was the source of it... So I can relate with Devin and his memory loss... Coming to this Dr Walter, I am cent percent sure this guy is the one who is sending weird letters to Leena... The one who Francy and Devin dying to find out... I think he might have been her treating doctor and have fallen in love or more like obsession over her while seeing her striving hard to stand and live happily in her life... She is receiving all these anonymous letters only in these three years... After analysing all these, I came to this conclusion... I may be wrong may be right... but idk...
Leena suffered so much because of those heartless people, Devin was her savior and the force that made her keep on living her life to the fullest. after this chapter, I anticipate the truth about Devin's memories will be revealed soon but I hope Dr. Walter isn't the stalker if by chance he is the one then I think he has a hand in Devin's lost memory
