She should have known it was all too easy but Molly was so relieved to find out that Rogue wasn't a leviathan that she let her guard down for a full five minutes before everything went wrong. She had her head turned to answer Rogue about her mutation when the man in the lab coat stepped out into in front of them and Sam's arm whipped out to keep them from flying forward when he slammed on the brakes. "Shit!"
When Sam looked at her, Molly knew immediately what he was about to do and she nodded. Can't go around it, can't run from it - there was an expression Chase used to use 'FIDO - Fuck It. Drive On'. If ever there was a time for it, it was now. She curled her fingers around the dash as the truck picked up speed, bracing herself for the impact . The impact wasn't as bad as it could have been but the truck tipping over threw Molly into action. She followed Sam out, grabbing the bottle of liquid Borax with one hand and grabbing Rogue's coat with the other - half helping her, half dragging her until they were all out.
Ripping the cap off of the bottle Molly took several steps forward while Mr Lab Coat's hands were full. "Hey! That truck belongs to a friend of mine, you asshole!" She waited for him to turn his head towards her before flinging most of the contents of the bottle in the leviathan's face and quickly backpedaling while the creature screamed and his true face came through the human face.
