Shawn nodded tightly to Ianto, quickly picking up the can of Weevil spray and bracing his gun against it. He jumped up on three with Ianto, spraying continuously and shooting when the opportunity presented itself. Eventually the Weevil fell to the ground under their onslaught; Shawn could hear Juliet adding to it in the background.
"Not exactly," Shawn turned, looking at Juliet warily. She didn't look like she was going to run screaming; a reaction that would have surprised Shawn coming from a cop as level-headed as Jules. He looked towards Ianto, a subtle nod of his head asking whether or not they should retcon her. They'd probably have to take her back to the Hub and let Jack make that decision, considering she had been searching so fixidly for Shawn.
