Jon wanted to tell Sansa the truth, or at least a believable version that didn't sound completely ridiculous. Lasting bonds and relationships were formed and maintained by being honest and truthful. And sooner or later, his magic would be exposed, and it would be better if Sansa knew beforehand. In his previous world, he had been alone for more than two hundred and fifty years, and while he thrived on fighting and delving into the deeper mysteries of magic, he still longed for family. Other things would come and go, but the real family stayed true. His parents, James and Lily Potter, lay down their lives for their child without a second thought. Sirius was a godfather who, despite all his flaws, gladly died for him. Even his former wife, Daphne, had loved, supported, and helped him full-heartedly. Daphne had also saved him from trouble of his own making multiple times, despite having to marry him because of a magically binding contract.
