Six months after that Harrison Wells was the Reverse Flash, their investigation into him had gotten nowhere, which meant it was time for a change of tactics.
"Joe thinks we should start over from the beginning," Barry told Kara over the phone while she was on her lunch break at work one day.
"Which means what, exactly?" she asked.
"Doctor Mcgee told me that after the car accident that killed his fiancee, it was like Wells became a completely different person," Barry replied. "So Joe and Cisco are headed to Starling City to see what they can find out about the accident."
"Ah," Kara said. "And I assume you'll be running point with Eddie on any cases that come up while Joe's gone?"
"Uh huh," Barry replied, with a rustling on the other end of the call that suggested he was nodding to himself as he spoke.
"Ok," Kara said. "Well, tell them to say hi to the team over there if they see them. And keep me in the loop."
"Will do," Barry replied.
"About your cases too," Kara clarified. "Not just whatever happens with Wells."
"Right," Barry said. "Got it." Then he hung up, leaving Kara to her thoughts and her work as her lunch break drew to a close.
A few days later, Kara heard from Barry again, in regards to her request that he keep her in the loop- he was after a shapeshifting meta named Hannibal Bates, who was responsible for a string of robberies wherein the suspect pleaded innocent despite having been caught on camera committing the crime.
"Wells and Caitlin warned me that I can't let him touch me while I'm out as the Flash because then we run the risk of him exposing my identity," he said. "Not to mention that we don't know if he would absorb my abilities when he took on my appearance. I think it's probably safe to assume that same thing goes for you as well."
"Got it," Kara said. "Hands off the metahuman. If I happen to run into him, that is."
"Hands off the metahuman," Barry agreed. "But yeah, just keep an eye out. Anyway, Eddie and I are about to go and talk to Bates' grandmother, so I will let you know if we learn anything."
"Alright," Kara replied, and this time it was her turn to end the call, and as she shoved her phone into her pocket and went about her day, she wondered if she should be troubled by the fact that over the last few days, she and Barry had talked over the phone much more than they had in person. After a moment's reflection, however, she decided that the answer was no, since they'd both had a lot going on lately, not to mention that Kara had been keeping her distance from STAR Labs as much as possible over the last six months, since she wasn't sure how much she could stand to be around Wells, knowing his secret, and not confront him about it, and she hadn't wanted to push her luck. If he found out that they were onto him, then all of their hard work would have been for nothing, and Kara didn't want to be the one responsible for ruining it.
First thing the next morning, Barry came charging into the bullpen just as Kara was sitting down at her desk, startling her with his sudden appearance.
"Barry?" she asked, noticing the panicked expression on his face. "What's wrong?" Instead of answering, Barry just jerked his head toward the file room.
"I need your help," he said once Kara had followed him inside.
"Yeah, I gathered that," she replied dryly. "With what?"
"When Eddie and I went to talk to Bates' grandmother last night," Barry said, "it turned out to be Bates pretending to be her, and when he realized that we were onto him, he ran off. At some point during the chase, he must have managed to get a hand on Eddie, and then he…" He trailed off.
"He what?" Kara prompted.
"He killed two cops," Barry said. "While wearing Eddie's face. So now Eddie's about to be put on trial for murder, and he'll go to prison for a crime he didn't commit unless we find some way to prove his innocence."
"Alright," Kara said. "So what do you need from me?"
"I need you to put your investigative skills to use," Barry replied. Then, a moment later, apparently as an afterthought, he added, "Please. Just dig up any information you can on Hannibal Bates. Look for anything that might clear Eddie's name."
"Okay," Kara said, nodding.
"And keep me updated!" Barry called as he headed for the door, and then he was gone. The next time Kara saw him, he was acting strangely. Not only did he seem to have forgotten all about the whole ugly mess with Eddie, but when she reminded him about it, he seemed utterly unconcerned by the fact that Eddie would go to prison for a crime he didn't commit unless they managed to catch Hannibal Bates, which was utterly unlike him. She called Caitlin to find out the cause of Barry's odd behavior, as she still wasn't sure if she wanted to risk stepping foot in STAR Labs. Caitlin told her that the reason Barry had been acting so strangely was because, at some point after he'd asked Kara to look into Bates, he'd had a run in with the person in question, who'd knocked him out and taken his place.
"Thankfully, this didn't happen while Barry had the Flash suit on," she said. "And Wells caught onto him before he did any lasting damage. And because of this, we now know that Bates can't take on someone's abilities when he takes on their appearance."
"So, hands on the metahuman," Kara surmised.
"Hands on the metahuman," Caitlin agreed.
"Alright," Kara said. "Thanks Caitlin."
"Anytime," Caitlin replied. "Though I'm not sure why you've been avoiding STAR Labs lately."
"I haven't been avoiding STAR Labs," Kara lied. "I've just been too busy to visit lately." Then she hung up before Caitlin could interrogate her further and catch her in her lie.
The next time she heard from Barry, it was from the real Barry, who told her that Caitlin had developed a serum that would neutralize Bates' shapeshifting ability, and that it, in combination with whatever information Kara had been able to find on him, might just be enough to clear Eddie's name. She gladly sent along everything that she had gathered, eager for them all to be able to put this whole mess behind them.
The next time Barry got in touch with her, a few days later, it was to let her know that Joe and Cisco had returned from Starling City with further evidence not only that Harrison Wells was the Reverse Flash, but also that the Wells they had been working alongside for the last year may not have been the real Harrison Wells at all, which seemed to be a recurring theme lately. Armed with this knowledge, Barry and the team- minus Wells, for obvious reasons- planned to explore a previously secret room they had found in STAR Labs following Joe and Cisco's return. Kara wished him luck and bade him be careful, and she could only hope that he and the others would be safe.
