I was thinking it was Mrs.Shore’s son the Magician who was mentioned but we only saw his back, because the only that reversed time looked younger and had blue eyes like Mrs. Shore. But that’s just my theory
Same!!! I thought that too
At first,i thought it was the younger bro and then i thought it was the magician but then we see the asshole dad having memories and headache which might be the side effect of using high complex magic so thats how i ended up at mu current guess
But as you said,it could be the magician
No matter what the father does now,im gonna hate him.i kind of have a feeling that he was the one who reversed time,but that aint gonna earn my forgivenesss
