say he was your father figure means say nothing. since he bit you and Scott (you, actually, was the first one) you always were in his side. you understood his motive and goal clearly and you helped him. then Derek finished him after getting burned by Molotov Cocktail off and became an alpha. but you never was Derek's beta. you neither had a pack bond with Scott and his pack. but you do with Peter

it returns after his resurrection and never disappear. you felt when he get back to live, you responded to his roaring call everytime. but he wasn't an alpha and it pissed him off. that's understandable. his family always were a protectors of Beacon Hills and now non of Hales had a alpha spark, but Scott McCall. he wanted it back. and now you against it. Scott is your friend after all. he gave you a chance and it worked. you told Peter you won't be on his side if he will do his plan, but you also give him a chance you change his mind. and he didn't use it
