Seems like Gray has a changed personality in this life. He seemed more vicious and bitter last time...or it probably has to do with change in Aaron. If Gray is out to destroy Alistair, he might have misunderstood Aaron in last life since Aaron wasn't openly opposing his father then and he extended his revenge to all the Hales. I've a feeling Gray will help Aaron this time..
Gray hate Aaron in the past life because he acted too cold like his father. Which makes me believe that Alister maybe Gray’s father and he hurt Gray’d mother because of how cold he was. That’s why he hated both Aaron and Alister in the past life. But I think because Aaron going after Alister in this lifetime , they might end up working together. That’s just my opinion. I think they might be half brothers .
