It could be!! Or maybe they didn't know it was Alex's house until he tried to attack them, then Luke sense it
and he suddenly throw the chain and fundo to immobilize Alex and tried to kill him but when he saw Luke's coolness or something, that's when he
started admiring him?? And Luke was like, "WHAT THE!?" xDD
And offered that they can visit him there anytime as compensation for he's surprised attack on them. Note that Luke was rather pissed cuz he was about to attack Ray back on that surprise attack..xDD
