That clifhanger is just cruel man lol
When Luck gave the key to Raymond, i was kinda expectimg this (Sadly, since Luck is my favorite character), but i think his relevancy in this loop is anything but over.
I have an theory that this could not be a direct sequel of Ray and Jacks loop (1s Luck/ 2nd Ray/ 3rd ? /4th Present) since there are some visible diferences.
Or there was an Loop before or after Lucks loop that happened before Rays (I still cant get Arthur getting the secret room out of luck and beeing hyper sus in Raymond 1st try when he and Lewis were hiding stuff).
Still, Lotte is still the most suspicious person, and i ll stand by that.
Great update, and waiting for the next!
