Cisco was surprised when Oliver entered Jitters with someone else.

"Oliver, who is this?" Cisco asked, playing dumb.

"You can drop the act Cisco. She's like us. She remembers." Oliver told him and Cisco dropped the act and pulled Kara into a hug.

"So, what exactly is going on here?" Kara asked.

"I asked Oliver to help me take down one of Barry's greatest enemies before he can even become that." Cisco said.

"You mean by killing him?" Kara assumed.

"Actually no. By destroying the thing that turns into DeVoe into the Thinker, we not only stop him, be also prevent another one of his greatest enemies, Cicada, from being born to." Cisco said and Kara nodded.

"Okay, I'm in. Where do we go?" Kara asked.

"This is DeVoe's address and this what you're looking for." Cisco said, showing them an image of DeVoe's thinking cap.

"So, we destroy this and prevent the Thinker from being born." Kara said.

"Exactly. And the accelerator is going off in a few days, we need to hurry." Cisco said and Kara and Oliver nodded.

"Let's go." Oliver said and Kara nodded as they began to walk out.

"Oh and Cisco, after that, I need to talk to you about designing my suit, since while the guy who did it originally was great, if my understanding is correct, everyone on this earth prefers you to make their suits and I want to see what you can do for mine." Kara said and Cisco grinned.

"Absolutely." Cisco said, honestly excited about getting to make Supergirl's suit this time, since it was honestly the one suit he'd been dying to make, but knew that she didn't need him to make her suit before but now she did.

"We need to get moving." Oliver said and Kara nodded as they left Jitters.

"So, what's the plan?" Kara asked as they stood outside the currently empty DeVoe house.

"I'm better trained in the art of infiltration than you, but you can be my eyes and ears. Let me know if they come back and also see if you can point out where the cap is." Oliver said and Kara nodded.

"Copy that. It's nice to be teaming up again." Kara said.

"We should do it more often and don't you dare tell anyone I said that." Oliver said and Kara rolled her eyes as Oliver put his mask, not his Green Arrow gear on, since he did not need the city thinking the Green Arrow was a thief.

"Good luck." Kara said.

"Let's do this." Oliver said.

"Also see if you can grab DeVoe's plans for the cap so we can destroy them as well." Kara said as Oliver nodded as he moved to enter the house through the window and then quickly disabling the alarm thanks to a device Cisco gave him.

"Where am I going here Kara?" Oliver asked as he moved through the house.

"Looks like it's in the safe hidden in the master bedroom." Kara said she x ray visioned the house.

"Got it." Oliver said as he headed up there and easily cracked the safe before taking not only the Thinking Cap, but also the plans for it out of the safe.

"I got what I came for." Oliver said as he moved to escape through the bedroom window with a cable arrow and then reactivating the alarm.

"Nice job." Kara said as she joined Oliver.

"Yep, now get rid of this junk." Oliver said.

"Gladly." Kara said as she used her super strength to crush the cap beyond repair and used her heat vision to burn the plans to ash.

"Hopefully that will put an end to the Thinker." Oliver said and Kara nodded as they headed out.
