Self-arrested
Jade Star asked for a oneshot of Emma (as the Dark One) locking herself in Regina's vault and Snow staying with her.
Melis sorry but that sounds a bit complex!
kindguest I'm sorry but I'm not sure I understand at what point you're talking about.
"I thought I said I didn't want anyone here." Emma said quietly. She could hear the faint sound of soft, ragged breath. Since she'd became the Dark One she'd found all her senses had heightened. Even just the sound of the breath was enough for Emma to know her mother was still somewhere in the vault.
"I wasn't going to just leave you here, Emma." Snow said, emerging from her hiding place. Emma clenched her teeth together in rage.
"I already told you all- I'm dangerous." Emma hissed. "And now that I've sealed myself in I can't undo it so you're locked in here with me. How could you be so stupid?!"
"I'm not being stupid," Snow said, moving cautiously closer to Emma "I'm being your mother. You are my daughter- and you cannot be alone just now."
"And what about Neal? What if I kill his mother?"
"I am your mother too." Snow reminded her. She stepped even closer and took Emma's hand- ignoring the way she flinched. "And right now you need all the love you can get. Your father has Neal just now. And when you realise soon that we aren't leaving you regardless of how dangerous you think you are and release us from here we can swap. I'll spend some time with Neal and your dad can be with you." Snow assured her. "Emma- we're going to sort this. And while we do we will look after you." Emma wasn't sure that she believed her mom- but there wasn't really anything she could do about it right now. She had to focus on containing the hatred swirling inside her at all cost.
