Robert wasn't one of those who came along with Morgan. He always was careful when it came to supernatural, especially when encountering something he didn't know much about. Morgan had mysteries varied from suspicious healing powers, strength to supernatural proportions to her weird ability to figure out events that have happened. However the two did agree on things when it did to their job. 

Morgan had bolted towards the Guardian, fast like an athlete. Creature's abilities came quickly clear, far faster than it's constantly growing size would have assumed. But Morgan was one heck of an investigator herself; she evaded the blows coming from impossible angles and finally she hit her fist inside the being. The blow did... Something that made Guardian Halt for it's time. This is where Robert was about to take his toss, before the being started to move again. As in, it threw quite a blow to Morgan, who flew several yards through the air. Robert was left surprised at the sight. "Bloody..." 

"Well christ, this seems a bit out of our league." Jacob commented, noting their distinct lack of armaments to fit the situation. He had his pistol, Rob probably had his sidearm along with his homemade molotovs. Jacob did have a shotgun in his trunk, but he doubted that would do much more against a guardian spirit of such size. Silver bullets would still bother it though. 

"I suppose we'd oughta get its attention," Jacob offered, as he began advancing on the Guardian, pistol in hand. He didn't advance at a sprint, and made sure to keep ample distance between himself and the Guardian, trusting more on distance than his fast reflexes to prevent harm from coming to him- for as hardy as he was, unlike Morgan, neither he nor Robert would survive a blow like that without anything less than several broken ribs, and possibly a collapsed lung. 

He fired off his pistol at it a few times, more to get its attention than actually kill it- the silver bullets hissing as they burned into its equivalent of flesh. His shots seemed to suddenly stop the creature just as Robert lighted up one of his cocktails; quick glance at the PHI witches revealed though that Emma had done some of her tricks to temporarily stop the Guardian's movement. Both she and Beth had sustained some injuries doing their magic and it seemed only he and Jacob were left standing properly, along with... 

Mandy. Robert wasn't comfortable with her being this close to danger.  “Cover me, please! And don't kill it" Mandy yelled at the two. It was easy for her to say; as Robert made another look towards the Guardian, it gazed back. Seemed like the detectives were next threat for the being to defend it's precious Wallmart from. Robert didn't like the idea at all. He toughened up and prepared for a sprint. However, the creature's movement stopped. If Robert had to guess, the being seemed... Confused for a moment. 

"Our peashooters won't do much good... Get a vehicle or grab those bottles, let it chase us!" He yelled at Jacob. He then focused his attention at the Guardian as it slowly turned towards Mandy and the witches. "Stay away from them" Robert yelled at the spirit and angrily threw his molotov at the creature. The bottle crashed and the gasoline inside made a fiery ball of flame at creatures side, some of the liquid spraying over the Guardian and igniting pieces of cheap decorations. It did definitely make Guardian angry as it was being tainted by something impure. Robert quickly ignited two other bottles before grabbing them and making a run around Guardian. 

Sprinting for his car as Robert began lighting molotovs, Jacob vaulted across the hood of the vehicle, and threw himself into the driver seat. He started the car with one hand, while another popped open the cover of the sunroof. He revved the engine a few times to get it running, and threw the car into drive. Skidding over to where Robert had ran, Jacob reached over and threw the passenger door open. 

"Get in!" Jacob yelled. Robert didn't think twice. He threw ran at the free seat, throwing one of his molotovs as he made his escape.
