Lock's grin remained even as Carver grabbed his throat and pulled him away from Lillith. He grabbed the vines near his throat to keep his own weight from pulling him down, then swung his body to hook his ankles and tail around her vines to further mitigate any damage to his neck.

"Oh, come on, Carver," Lock said cheerfully. "She [i]already[/i] got you back for it."

His tail tightened around her vines to bind them together, but that he didn't otherwise try to fight back said enough: all he wanted was a laugh at her expense for the moment, and nothing more.

"And bringing it up now will just put a target on [i]both[/i] of our backs. I'd rather keep her attention on Barrel."

Which would unwittingly clue in to the rest of the group what sort of mishap happened with who, but he didn't care. Lock hung like a sloth from Carver's vines, then turned to Carmilla. He gave her a weird shrug while he held onto the vines. 

"Wasn't us," he said, then gave a knowing glance to Agatha. "For [i]some[/i] reason, we can't get into the building if the shop's not open."

Lock grinned at her. He knew [i]perfectly[/i] well about the hexes the witches put on their building to keep him and his siblings not only out of the shop when it was closed, but the living areas upstairs as well.
