Aster didn't notice as his usually sensitive feet got froze to the ground. Instead the pooka just sat back on his heels, ears pressed impossibly flat against his head, staring at the sky light the spirit had just left. Aster felt a small whine escaped his throat.
That boy was not Jack just another spirit now. He doesn't know what has happened to Jack, but that spirit wasn't the fun loving winter spirit Jack Frost.
Jack Frost had always been unique. A spirit with no memories of his life before he was a spirit. A spirit with no idea why he was there. A child who was still a child but had the mind of an adult. And now a spirit who has forgotten everything, for normal spirits that would be the end of them. Spirits need to know who they are, it's a need all spirits have they tend to disappear otherwise, yet Jack has managed to survive three hundred years and has now forgotten everything once again.
Behind him Sandy was breaking North and Toothiana from their icy capsules. Besides being a little cold neither sustained any injuries. Jack had been careful to encase them enough so to hold them but not enough to harm them. He had even left multiple holes allowing air to circulate. Whether all this was by design or his magic subconsciously protecting the other Guardians they won't know. But soon they would find him. Hopefully in a better mood.
