"Maybe tracking her off of face cream would've been easier." Caitlin said as she, Harry, Felicity and Alex worked on using Overgirl's blood to track her.

"Supergirl-X's blood is filled with solar radiation- more than it should be- but if I could try to get that to act as a kind of beacon." Harry said.

"Hey, ahem. How do you do it?" Mick asked Caitlin.

"Do what, Rory?" Caitlin asked, a bit annoyed at him.

"Bring the other you out of you." Mick said.

"You don't want to know." Caitlin said.

"Sure I do." Mick insisted.

"It happens when I am scared or angry." Caitlin said.

"Oh. So if I were to, um, boo!" Mick shouted, making them all jump, but Caitlin just rolled her eyes as she didn't change.

"Nice try." Caitlin said.

"Boom. Whatever's going on with Kara-X's blood, it's intensifying." Harry said.

"Worse for her is better for us." Felicity said.

"Better for us for tracking her at least. We should have her location any minute." Caitlin said.


Barry and Iris were in the time vault when Oliver entered.

"Sorry to interrupt, but we got a hit. They're at a shipping depot outside Danville." Oliver said.

"All right. We'll get the band back together." Barry said as he walked out.

"Yeah." Oliver agreed as he followed.


After suiting up, Sara snapped her batons together in a staff as Alex locked and loaded. Laurel put on her sonic device and then her mask. Jax and Stein merged in Firestorm. Barry pulled his cowl over his head and his eyes crackled with electricity. Kara ripped open her shirt to reveal her Supergirl suit underneath. Oliver stocked up on arrows before putting on his mask and pulling up his hood as they all headed out.


"Supergirl and Firestorm are sweeping the perimeter." Green Arrow said to Black Canary, White Canary and Alex as Flash sped up to them.

"It's done. It's wall-to-wall Nazis in there." Flash said.

"Alex and I will take up breech positions on the northwest corner, if that's ok with you." Sara said and Alex nodded.

"S.T.A.R. Labs thinks they converted the sub-light generator- the Prism that they stole- into some kind of superweapon." Alex said.

"Speaking of super, theirs is our biggest threat." Flash said.

"Agreed. Let's take her out first." Green Arrow said.


Green Arrow entered the facility to see Nazis and prepared to shoot them, only to have the Flash take them all out.

"You couldn't have saved one for me?" Green Arrow asked.

"I'm saving Nazi you for you." Flash responded.

"There's no sign of the Prism." Alex said.

"Well, it's got to be here somewhere." Flash said.

"We got incoming." White Canary said as they were surrounded by Nazis and a streak of red lightning flew past them and Flash sped after it as the other engaged the Nazis.

"I see Their Flash, their Supergirl." Alex said as Overgirl flew past her.

"Yeah, I see them." Black Canary said.

"Where's their Arrow?" White Canary asked.


Harry was walking through the halls at STAR labs when he saw Black Arrow in the hall.

"Oh god." He said.

"There is no god." Black Arrow said as Harry back the way he came and set off the alarm, right as Black Arrow knocked him out.


Mick, Caitlin, Iris and Felicity were all in the cortex when the alarm went off.

"You and you, hide." Mick said to Iris and Felicity.

"What about Caitlin?" Iris asked as Mick looked at her.

"Things are about to get a lot colder in here." Mick said and Caitlin nodded as she followed him.


After being punched through a wall by Overgirl, Green Arrow came to see Overgirl preparing to kill White Canary and after coughing up some blood, he fired another kryptonite arrow at her, but she caught it and threw White Canary aside.

"Burn." Overgirl said as she fired her heat vision at him, but he managed to dodge it and the beams deflected back at her, sending her flying backwards.


Black Arrow had just exited the speed lab track as Mick entered and fired his gun at him.

"Afraid of a little heat?" Mick asked.

"No. I'm afraid of nothing." Black Arrow said as he fired a rope arrow and tied Mick to a pole, knocking his gun out of his hands.

"Bet you're pretty angry and scared right now." Mick said.

"I told you, I don't fear anything." Black Arrow said.

"Actually He was talking about me. Didn't think this through, did you? Just you against us." Killer Frost asked as she froze his bow and hand.

"I don't need to think to kill you." Black Arrow said as he fired some sort of photon blast that shattered the ice and sent Killer Frost flying back.

"Anyone else want to be a hero?" Black Arrow asked and suddenly, Speedy, Wilddog and Mr. Terrific appeared out of nowhere.

"They wanted to wait, but I didn't think we'd ever get a better entry line than that." Mr. Terrific said with a grin as he tossed one of his T-spheres in the air and they all attacked Black Arrow.
