Y/N and Barry both quickly turned, stunned by what they saw...Thawne had found them. He stood in the doorway, arms crossed.

"Hello!" he yelled again. "Are you two deaf or just stupid?" he shouted

Barry slowly brought his arms up in surrender, but Y/N didn't follow his lead. "No," she whispered under her breath, barely audible. There was no way that she was going to let him stop her.

"Put that down," he said motioning to the bottle in Y/N's hand.

"No," she replied almost instantly. "I'm not gonna put this down, and you are going to let us go," she added.

"Why would I do that?" he asked.

"Y/N," Barry said under his breath, almost as a warning to stop. Y/N could see him, the hate in his eyes as he glared at Thawne.

"Barry run," Y/N said stepping towards Thawne.

"What?" he questioned.

"Run," Y/N repeated as she approached him.

"I wouldn't bother," Thawne said. Barry caught on quickly and brought himself closer to Y/N, putting himself in front of her.

"Barry Allen, are you afraid?" he snickered. "You seem afraid..."

"You know who he is?" Y/N asked.

"All too well, now Barry. I already killed your mother, do I really have to kill your little friend too?" Thawne asked getting right in Barry's face.

"You're not gonna kill anyone," Barry said through gritted teeth.

Y/N could see that Thawne was distracted, she quickly ran in and made her move, getting a swift kick and punch in before he sent her flying into a shelf full of supplies.

Barry stepped up pushed Thawne up against a wall, his arm at his throat, "When will it stop Thawne? When will you quit wasting your pathetic life tormenting mine!" Barry shouted. "I hate you."

"And I hate you...sometimes I wonder which one of us is right?" Thawne replied.

Y/N had managed to sneak up on Thawne and stab him with a drug that would be enough to scare him off for now at least, once he was dealt with she let out a sigh of relief. Barry did the same and checked her over.

"I'm fine," she winced. "Just a little pain," she added. "Thawne doesn't know who I am does he?"

"No," Barry said. "He's from another time, apparently he's killed my mom, but he probably hasn't met you yet, that or it's a side effect of us being here and disrupting the space-time continuum," Barry explained.

Y/N nodded in response. "Are you okay?" she asked.

Barry nodded, "I think so," he replied. "What do we do now?"

"Now, we figure out a way to track this," Y/N said holding up a bottle of the speed drug, a smug smirk on her face. "And I have an idea of how to do it."

"Lead the way," Barry said motioning for her to do so.

Y/N grabbed Barry's hand and let him out of the room and down the hall and across to another room; one that appeared to be a medical lab.

"Where are we exactly?" Barry asked observing the area.

"The medical wing, my dad's office is right down the hall, these rooms have the most advanced computers in the entire facility," Y/N explained as she typed away until she suddenly stopped. She took a step back, her breath hitching in her throat.

"Y/N?" Barry asked faintly, stepping forward slightly.

Y/N then collapsed to the ground, her body shaking and cold, Barry was in shock of what was happening until he saw the blood seeping through her suit. He crouched down beside her.

"My dad," she said weakly reaching out for Barry's hand..."Get my dad," she repeated.

Barry nodded, before quickly running out the door and searching the hall for her father's office until he stumbled upon it, he quickly barged his way in.

"What the hell?" her father shouted.

"I n-need your help, it's my friend," Barry said reaching out and grabbing his arm as he began leading him towards the room where Y/N was.

"Pal, look I'm gonna call security," he yelled. His protests stopped when he entered the room and saw her...
