He hates it when she cries. It makes him feel powerless, like he didn't protect her enough.
When her father dies is the first time he sees her cry. She kneels there sobbing and he has to take her away from him. 10 years of searching, only to have to be ripped away after he's killed. And it breaks Hatter's heart.
She cries when she realizes he's there to stay. In her world, changing everything to be with her, because he loves her. He panics when she starts crying though, holds he face to look at him, wiping away her tears. Trying to get her to stop. Until laughing she tells him that it's because she's happy, and he feels a little better.
The next time is when he pulls out that little ring box, and asks her the question. Acting brave on the outside but inside praying to any and all holy powers for her to say yes. She laughs and cries all at once and when she agrees he lets out a happy yell and spins her around with his arms around her waist. And her tears trail behind in the wind.
Even when he sees her crying as she walks down the aisle he wants her to make her stop. Because he hates to see her cry and no matter how many times she tells him that they're happy tears he can't help but ignore protocol and bend down to kiss them all away even before the opening is down being said. And she laughs because her Hatter is the only one who can make her stop crying.
A/N: Ladies and Gentleman this is what happens when I sit down to write a finals essay due a 10 am tomorrow, lol. All I can say is Woot for incomplete sentences because apparently I love them right now. Don't worry, more grammatically correct stories are to come!
