I can’t stop picturing it so, here, picture this with me.
Imagine this, Derek swearing Braeden and Parrish and Chris Argent to secrecy about his full shift change.
Derek leaving town with Braeden to have a break from the shitstorm that is Beacon Hills, possibly forever.
Derek coming back to town but not wanting to bother Scott so he checks in on him in his wolf form.
Stiles thinking he’s going crazy because he’s pretty sure Padfoot from Harry Potter is following him.
Scott feeding the “stray” that keeps hanging around Deaton’s vet’s office.
Deaton giving the “stray” a knowing look because he looks just like Talia so he’s not fooled.
Sheriff Stilinski sharing hotdogs with the “stray” when he keeps hanging around the Sheriff’s office and swearing him to secrecy.
Lydia being walked home after a party by a very large but incredibly friendly “stray”.
Kira rolling around on the grass and playing with the “stray” when she lures him back to her place with the promise of cookies.
Derek finding that doggie cookies are actually quite tasty in this form.
Liam having the “stray” help him out when he’s practicing for lacrosse when Scott and Stiles are busy by the stray constantly running after the ball and bringing it back to him.
Parrish having a nightmare about the war mixed in with all horrific ideas of what he might be and waking up to a whining and scratching at his door, going to open it to find what he’s just going to tell himself is simply a dog outside and it just lets itself in, curls up on his bed and sleeps with him. It keeps the nightmares away so he’s not going to acknowledge that he knows it’s Derek.
Then one day, the pack are hanging out and the “stray” lets itself in through the doggy door Scott installed when it kept coming around and just flops on the floor. Malia comes in with the food they ordered and just goes “oh, good, Derek’s here.” And everyone just stops and stares and have puzzle pieces come together.
Derek sheepishly shifting back, pulling a pillow over his lap and just going “hey guys. We’re having pizza?”
No one mentioning it when Derek still occasionally does all that stuff even though they know it’s him now.
