"Hey!" Molly yells, a slightly angry expression on her face as she lands on the ground, finally arriving at her destination. She quickly began to approach Nightmare "I heard that you were stealing people, quackidee! That's not okay! How would /YOU/ like it if you were stolen?" This is probably the most... 'Aggressive' she could be. "These people have friends, perhaps even families, yet you want to steal them?! Don't you know any better?" She quacks, loudly. "Release them. Now."
When he’d first heard her, he turned around grinning, expecting some regular person. But no, that’s not what he received. His smile was wiped off as soon as he had time to comprehend what exactly was coming for him, replaced with an open mouth of silent horror.
Nightmare backs up appropriately upon Molly’s approach, his cape opening completely so he could use both hands to defend himself from this duck. But he knew he couldn’t bare to touch the thing, he could hardly bring himself to do anything other than back off.
“Not here,” he whimpered to himself, “n-not infront of all these people..!”
With her quack he literally has to stay a scream, and does a pretty good job at it too. Honestly, anything and everything she says is lost on him because of how scared he is.
Nightmare floated over the tables where he kept his orbs, and when Molly passed that and still pursued him, he pressed himself against a wall, forgetting the power he’d found out about more recently and staying there.
“I-I just want attention, I didn’t even hurt them! M.. Most of them!” Nightmare explained, trying to force an incredibly shaken smile onto his paling face, “There’s- L-Lets settle this like normal r-reasonable people, there’s no.. N-No need to be so loud about this!”
Noise from his one explicit fear terrified more than anything. One could hear that in his forced laugh and withdrawn posture that he was literally scared shitless of this duck, despite being eight feet taller than it.
“W-What.. What can I do to get you to leave?”
He’s like, centimeters away from screaming.
