No the Alpha probably bit his sister 2 . I think they looked different cause Derek's older & Scott's like a cucciolo compared to him . & Scott can feel Derek when hes around - i think that means there in the same pack .
NOOOOO... WELL THATS IT PERIOD... SCOTT WAS BITTEN da THE ALPHA WHICH MAKE HIM PART OF THE ALPHA'S PACCK... WHILE DEREK BECAME A lupo FROM FAMILY HERITAGE SO DIFFERENT PACKS.. PLUS I THINK IT'S BECAUSE THEY R PRETTY... AND te CAN TELL WHO'S WHO AS A PURE WEREWOLF... (DEREK-BLUE SCOTT-GOLD ALPHA-RED)
