When Jon Sends Ghost Off With Tormund
After Jon is revived in season six, Ghost's appearances drastically declines. But the albino direworlf makes a comeback in season eight, where he's right in the thick of it all during the Battle of Winterfell. Ghost survives — and loses half of his ear in the process — but he doesn't stay in Winterfell for long. Jon asks Tormund to take the direwolf with him when the Free Folk head back to their home further North. The former King in the North leaves his long-time companion behind without so much of a "good boy." Poor doggo.
