Serena's instincts kicked in as soon as she heard Nick's first proclamation, and she swam towards him in swift, powerful strokes. A small part of her was glad that she was still wearing the dress she outfit she had chosen for the club, since the short dress allowed her to move without any hindrance. Of course, it was probably ruined by now.
The blonde woman got to Nick before she did, but a summer of lifeguarding at the beach had taught Serena that it would be better to stay close to the kid, just in case. If the plaque was any indication of the shit that was heading their way, the kid would need all the help he could get.
She blinked twice at the man vanishing in front of her. She had been half joking with the whole invisible hero thing, and was wholly unprepared to see a person disappear. That weird light had to be playing tricks on her, right? Right.
Left with no time to argue about the instructions, Serena nodded and took a deep breath, waiting for Nick to disappear before diving towards one of the plastic plants she had spotted earlier. Seven seconds wasn't very long to hold her breath, and Serena was a good swimmer. But still, she would have been lying if she said that a small part of her wasn't afraid of drowning in this god damn inky pool of shit.
