LOL True! But I kinda have this head!cannon where he watched over her for years before she managed to find her way back to him. His curse forbade him from being able to actually reveal himself, in his true form, to her or simply take her back to the Labyrinth with him. But something like this -- I doubt he could have resisted protecting her, and the anger of the Goblin King is truly something to behold as we all know! <3
