How hard would Bunny laugh if Jack dyed his hair? Not a crazy color like some of the kids were doing today.
Although Jack had to admit, all those colors looked absolutely stunning and he'd be lying if he said it didn't make his head turn sometimes.
But no. Not a crazy color, not multiple colors, not highlights or tips.

Just brown. He kinda missed it.

Before seeing his memories of his past, there had always been this...itch. Looking into the water, or the reflection in a window, his eyes always darted up to his hair for a split second. Something was just a little off.
And now, after having seen his past self, he could identify why. He was a brunet.

Now, don't misunderstand, Jack loved his white hair. Of course, it matched his job as the bringer of winter, but it also matched the snow he made and that made him feel connected to it. The vibrant gleam it would give off when the sun hit it just right always made him smile.

The only issue was that he didn't get a choice.

Manny did.

Manny was the one to change his hair color.

Manny was the one to decide that his brown hair didn't fit 'Jack Frost'.

At first, he felt anger. How dare Manny change a part of him that was so important.
But then again, Many did save his life, so maybe he should be nicer.
Okay. If he couldn't be angry, then he'll just be sad.
Sad because one of his best features -at least in his opinion- was forever gone, ripped from him in death and changed without his permission.
Sad because there really wasn't anything he could do about it.
Sad because this problem wasn't an actual problem and he should just get over it. It wasn't hurting anything except his feelings.

Alright, it's decided. He'd mourn the loss of his brown hair and accept the fact that he couldn't do anything to fix it. Yes. This was a good plan.
Except, he really didn't want to be sad. He'd spent so many years of his immortal life questioning everything, wondering why he existed, feeling sorry for himself. He was tired of feeling sorry. But if he couldn't feel sadness, the only thing left was numbness. Nothing. Ignore the slight pang in his heart every time he looked at his reflection and pretend this issue wasn't an issue. He sighed. This wasn't working.

Anger wasn't worth it. Sadness was useless. And Numbness hurt.

What else was there? Acceptance.

He could just accept it and move on.

But he didn't want to forget the sting he felt. He didn't want to forget his brown hair.
He looked down to his left, Sandy finishing his last sentence, ending with a soft smile that reached his eyes. Yeah. Sandy was right.

Accepting his white hair didn't mean he had to forget his brown hair. He could still feel remorse and hurt and anger and sadness over his loss, but he shouldn't let it take over. At the end of the day, if he really wanted to do something about it, he had four other people to back him up.
"Thanks Sandy. Sorry to bother with this. I know it's not super important"

Sandy patted his arm and shook his head. If it was causing Jack this much distress, then clearly it was important.
But as long as the boy knew he had the Guardians behind him in whatever decision he made, Sandy had done his job.
