Answer to the prompt: "You heard me. Take. It. Off." From the same universe as the "I'm pregnant" Drabble.

He knew from the moment Mary Margaret came up with the idea, that it was a bad one; but Mary Margaret had been a shadow of herself since David decided to try to save his marriage with Katherine, and Emma just couldn't say no when she saw that spark return to her friend's eyes.

Now she realises she should have said no from the start. The moment she saw her ex-boyfriend walk in with a prosthetic hand, she realised she shouldn't have agreed to the costume party. There was an uncomfortable silence until Killian decided to laugh it off and act as if it didn't bother him. But she knew better. She knew him better; she saw the hurt in his eyes and she had to ask herself why in heavens she thought inviting Neal was a good idea.

She counted to ten to try and calm herself down before storming over to Neal and grabbing the hand holding the prosthetic one.

"What is this?" As much as she tried to hide it, the anger was evident in her voice, and Neal must have sensed it because his smile faded from his face.

"I came as Killian." Emma closed her eyes without letting go off his hand and started breathing heavily. She was trying not to let all the anger she had bottled up inside towards the man come out. Before opening her eyes she felt the warmth of a hand pressing her shoulder and Killian's whispering her ear; "Emma, is alright."

But she was having none of it, not when her damn ex had hurt her best friend's feeling at her own party. Without reacting to Killian's plead she focused her eyes back on Neal.

"Take it off."

"…what?"

"You heard me. Take. It. Off."

"C'mon ems it's just a joke…" Neal seemed to be growing angrier himself which only made her squeeze his hand harder.

"Take it off or leave my house." Neal huffed as if bothered by her request and took off the prosthetic hand.

"Happy?" She kept glaring at him, wondering if she should punch him or not before kicking him out of the house, but the hand on her shoulder made its way to her arm and started moving her towards her room.

She was still seeing red when Killian closed the door behind them and made her turn around to face him. "You didn't have to do that, you know? It's not the first time someone makes fun of me for this." Killian held his arm in front of her eyes as if to prove his point.

"Doesn't mean I'm gonna let anyone do it in front of me." She dropped her gaze to the floor when Killian's eyes became full of emotions she wasn't ready to name. "Besides no one can make fun of my best friend unless it's me.
