"Hello Jack. It's been a while." Harry smiled as he watched his first friend's eyes widen in shock and disbelief Those eyes darted to look at the other Guardians for a moment before settling back on him.
"No," Jack took a step back, stepping onto the air "This isn't real. You're dead. I felt you die."
"You did," Harry agreed, gentling his tone some "Because I did. It just...didn't stick. It's kind of a long story all things told, but I'm alright. And I'm here now." He stepped forward as well, holding out a hand for his friend "I'm sorry I left, but I'm back now." There was a long pause where the Winter spirit simply stared at him, wide-eyed and as frozen as the ice he created, but that moment didn't last. One more frantic look at Sandy was all it took for the older being to seemingly accept the reality they lived in and launch himself into the man he'd thought dead, crashing into him with considerable force and knocking them both over so Harry landed on his back with Jack on top of him, arms wrapped firmly around him.
"You're alive!" It was a cry of jubilation choked with tears of relief and Harry was swift to wrap his arms around the thin being in return, ignoring how his breath was knocked out of him as they went down.
"I'm alive," he agreed once he felt he could "And I'm not leaving again. I get to stay with you now." Jack pulled back at that, questions clearly swimming in ice blue eyes, causing Harry to chuckle quietly. "Like I said, it's quite the story. But the end result is I'm alive and I'm not aging. I'm not a spirit like you are, but I'm not really human either. I'm not going to be dying any time soon, if ever." He smiled warmly as tears pooled in the eyes he'd missed so much, watching as Jack took in this new world they were living in. A world where Harry was alive and wasn't going to be dying in a couple decades or a century at most. It was a good world to live in, if Harry was one to judge.
"I want to hear that story," Jack told him as a couple of tears broke free and froze on his face.
"You're not the only one, Mate," The Easter Bunny cut in, drawing the attention of the immortal teenager to the smirking rabbitine face "He told us he wouldn't be answering our questions until you got here. So now that you're here we all want to hear the story."
"Yes, sounds like an interesting tale," Santa Clause agreed with what seemed to be his typical booming voice. Jeeze that man was loud, but at least he was friendly. "We go sit in room with comfortable chairs, yes? Much better for stories." Jack let out a slightly shaky chuckle at that before nodding.
"Alright," the Winter spirit agreed before floating up and off Harry and offering him a hand up, which the Master of Death happily took, for all he didn't actually need help standing. Rather unsurprisingly, neither of them let go of each other's hands once they were both upright. Instead, they continued to cling to each other as Santa led them to a room with several comfortable-looking chairs and a couple of coffee tables, which the yetis had placed trays of snacks on. Harry was further unsurprised when Jack decided to forgo his own chair, instead settling onto the armrest of the chair Harry himself sat in. He didn't mind though. He'd missed Jack fiercely. And it was nice to see how Jack had missed him too.
"So, are you all ready for my story?" He asked, glancing around the group that had settled into the chairs around him, earning him rather firm and excited nods in reply. "Alright then. It all started a couple of weeks before my eleventh birthday..."
