"Mom I'm HOME!"
Carrie Bennet emerged from the kitchen, her eyes red from crying. She took in the sight of her son in the arms of the legendary King of Winter himself, the teen of snow she had often seen playing with her children on one of his famous Snow Days, and now had come bearing her son. Her son that she had given up ever finding again. Rushing forward, she took her boy in her arms, crying happy tears as she held dhim close.
"Jamie! Jamie Bennet don't you EVER do this again!"
Jack turned to leave.
"Stop right there, Jack Frost."
He froze, eyes wide "You...you can see me?!"
"I have seen you for a long time, Jack." Carrie laughed gently ."You saved my boy...didn't you?"
The Winter sprite blushed, and wrung his hands. "Actually, I'm the one who—"
"Yes!" Jamie cut in, a panicked gleam in his eyes "He saved me!"
"Jamie, enough. She has to know." Jack said honestly, looking Carrie right in the face.
"I took Jamie. I needed a prince, and he stumbled onto me when I...was not in my right mind. I kidnapped him, and I...I..." he started to sob. "I'm sorry. I understand if you no longer want me anywhere near him. I understand if you cast me out. I understand-"
Carrie surged forward and embraced the Guardian of Fun, ignoring the cold he brought to her skin as she pressed his head into her shoulder, rubbing his back and crying happy tears.
"Enough, Jack. I don't care about all that. You brought my Jamie home alive, and that is all that matters to me. You are always welcome here, Jack Frost."
Jack smiled nervously.
You say that now...but once you see his back, I'll be cast out.
But he never was, even after a bath revealed the frostburn brand on the child's flesh. Carrie was horrified at first, but after Jamie explained everything the mark meant, she felt at ease. That brand meant her Jamie would always be safe, that all he needed was to yank on the bond, and the Winter Teen would come rushing in, to save her son. Likewise, all Jack had to do was summon him, and he would be pulled from whatever danger lurked ready to spring.
Carrie was slightly less enthusiastic about the pale skin Jamie now sported, but that too, had some redeeming to it. Her son would no longer be at the mercy of the elements in Jack's season. He wouldn't ever freeze to death, nor would he get chilled by the wind.
Yes, Jack Frost was a Guardian, even when his heart froze over. That was what she loved about him. That is why he was still allowed to be with Jamie, with Sophie...
That was why she trusted him. That would never change.
