A.N. This is theory is entirely mine apart from Keefe being a Mesmer
So I think it's suspicious that at the the end of Legacy Oralie never said "Stellarlune" so I think before she can say it Elwin is going to call Sophie and tell her Keefe has woken up.
GUYS HOW AM I THE ONLY ONE THAT REALISED THIS! KEEFE IS NOT ON IN A COMA! SOPHIE ASKS ELWIN AND HE SAYS NO! I think everyone just saw the word coma and yeah...
So anyway I think he's going to manifest as a Mesmer because Gisela was going to take him with her and maybe Sophie as well to force his hand?
Then he will use his Mesmer power and accidentally hurt someone, Ro maybe?
Then Sophie will heal him and in the process she will realise Keefe loves her and find out her true feelings.
