I will never understand why people think Peter isn’t capable of love and affection and even loyalty.
He loves his family and he is loyal to only them. Why else would he stick around when he doesn’t need to? Because of his family.
If Malia hadn’t been his daughter I think Peter would’ve gone with Derek or maybe down to stay with Cora when they each left. He only stayed because of Malia being his daughter.
Hell, if they had gone with Jackson being his son Peter would have left when Jackson did (and the other two were gone) I bet.
At least this is my opinion and headcanon.
Granted it's been years since I've seen this show, but...IIRC didn't he also kill his own family in pursuit of power? Like yeah, sure, once he HAS power he is willing to protect his family if it costs him nothing and gives him an advantage, but he's also a backstabbing lying selfish traitor, and would convince Derek to stay if he saw some angle where he could benefit.
