after watching this movie i can't even tell anymore who is Talos. riley or the mummy? the mummy calls riley "highness". talos was pretty damn powerful and wouldn't call anyone that. was riley actually a reincarnation of talos' past lover or what? that'd just be damn weird.
I know what you mean, I didn't get the ending either. I wasn't sure if Talos just used Riley's body or Riley was the reincarnation of Talos. The ending is very unclear.
Perhaps he was refering to his wife the princess, she was the real royal. Talos was just given a title. I think the ending was weak they tried to do a twist that just fell flat. How did each individual get the specific organ in this time?
Seven of Talos' followers each consumed one of his organs, and all of them had been reincarnated in the present day (one of them as a dog).
When Talos reclaimed 'his' organs from each of the reincarnated, he absorbed some of their DNA. That's why, when we first see Talos' incomplete new body at the end of the film, his legs have backward-facing joints like a dog's hind legs - it's due to the canine DNA.
Riley was the reincarnation of Talos' wife, the princess who consumed his heart. My theory: as the heart is the most important organ, and blood pumps through it to the rest of the body, after Talos placed it in his chest Riley's DNA proceeded to overwrite the DNA from the other reincarnated followers, thus transforming Talos' body into a duplicate of Riley's.
