At first

Scott tells himself that it's for the pack, it's for Peter , and that it's for their fallen- especially Stiles- when he writes letters to Derek.

Scott will write to Derek because they need him (Scott doesn't need him), he will write to Derek because of what Derek used to be to Stiles( because he owes Stiles that much)
He will write, not because Scott is as broken as he is, not because of what Derek was to him and definitely not because of what Derek wasn't to him.
