Well I am unsure as to whether or not he knows of the others but he most likely will put 2 and 2 together and realize that they aren't acting according to what he remembers. Also I believe the previous chapter where he's finally shown after so long is when he most likely recieved most of his memories but don't quot me because I'm getting this from memory of a spoiler that he will remember
Well crap. Does that mean Laurence also remembers the past. If he does that’d be a plot hole. Tia remembers because she casted the spell. Cedric remembers because he was in the vicinity of the spell. And Lisia remembers because she originally had the divine powers that now Tia possesses. Why does Laurence suddenly remember? Also Tia. Now is the best time to get rid of her. No one knows where he is and the emperors attendants can be blamed because they were supposed to oversee him.
