Even with Damon's helpful information Rebekah hadn't expected tracking down Katherine would be easy, and it wasn't. The girl had five hundred years' worth of experience running and hiding from her least favourite brother, and at times her favourite brother, so there was every chance this would turn out to be a fruitless endeavour. That Katherine would use the cure in some nefarious way before Elena and herself could catch up to her. Or despite their head start someone else would beat them to it. Or Katherine would just keep running, Rebekah helplessly trailing behind her for years. Decades. Centuries.
At the start of this endeavour waiting so long to get her hands on the cure had seemed unbearable, and then beyond unbearable when she teamed up with Elena. Then ironically because she was in a team with Elena suddenly years seemed highly tolerable. Possibly even decades and centuries, just so long as Elena's talented little tongue and forever tight fuck holes were available to Rebekah at all times.
However, for better or for worse, it didn't come to that. In fact it only took a week of searching in between rounds of really hot sex to find the bitch and, after a brief tussle, sit her down in the nearest available seating area for a little chitchat.
"Where's the cure?" Elena asked calmly.
Katherine smirked, "What? No, 'I'm here to avenge my annoying little brother' speech."
Unfazed Elena replied, "People die, we move on."
Rebekah spared her a glance. Even after spending a few days constantly by this new Elena's side it was jarring to hear her sound so emotionless and detached.
It even took Katherine off-guard for a moment, the bitch staring at her doppelgänger for a few seconds before subtly smirking and then as if she was finishing Elena's sentence, "After turning off our humanity switch."
"So sad for the boys though, their special snowflake of human frailty, gone." Katherine then continued after a pause, even having the audacity to start getting up as she added, "Well, if we're going to be a while I'll go grab us some menus."
Katherine also made the mistake of pressing her hands on the table to push herself upwards, not even having the sense to immediately launch into super speed, although Rebekah had no doubt that was the ultimate intention. Before she had the chance Rebekah capitalised on the brunette's mistake and jammed the fork into the oh so easy target in front of her, namely Katherine's left hand.
Rebekah took a moment to enjoy Katherine's sadly stifled cry of pain and then calmly told her, "You're not going anywhere."
"I forgot how charming you were." Katherine spat.
"I'm surprised you remember me at all, seeing as you were so busy wedging yourself in between my brothers." Rebekah snarked back.
Clearly unamused Elena said, "Every minute you two waste with your yapping is another minute for Stefan and Damon to find us."
Seeing her current ally's point Rebekah grabbed hold of Katherine's chin and yanked it towards her before repeating Elena's earlier question, "Where's the cure?"
Katherine smirked, "Sorry, I'm on vervain."
"Oh, I get to torture it out of you, fun." Rebekah said, letting go of Katherine, for now.
"Why do you two want the cure anyway?" Katherine asked.
"The question is, why do you want it?" Rebekah countered, "Let me guess, to kill Niklaus."
"I've spent the last five hundred years running from your big brother. I have no intention of even being in sniffing distance of him." Katherine said before smiling, "But, seeing as it can be used against him, I'm sure he is just itching to get his hands on it. I give him the cure, he gives me my freedom.
Elena faked sighed dramatically, "You poor victim. Where's the part in your plan where you screw us over and somebody dies."
"I have no reason to screw you over." Katherine said, and then when Elena let out a half-hearted laugh, "I know you don't believe me, but it is the truth. People change. I'm not the girl you think I am."
Rebekah forced the laugh and then used her super speed to grab Katherine's phone and toss it to Elena.
"I don't have it on me." Katherine protested, trying to avoid any more searching.
"I didn't think you did, but maybe there's something in that which will help us find it." Rebekah said as Elena look through the phone.
Checking Katherine's planner Elena noticed a simple note, meet Em, which begged the question, "Who's Em?"
Katherine hesitated and then simply said, "A friend."
"It says here you're meeting at two." Elena said, waiting for Katherine to volunteer more information. Unsurprisingly she didn't, so Elena added, "Fine, I'll just have to meet Em myself."
After mulling it over for a few seconds Rebekah said, "Mmmm, splitting up? Bad idea. Way too horror movie cliché for my taste. Especially when we can just stay here and torture the information out of her. Or for this mysterious Em to show up. You know, whichever comes first."
Elena raised an eyebrow, and smirked, "What's the matter Rebekah? Don't think you'd be able to handle Katherine by yourself?"
"Hardly." Rebekah scoffed, "I mean sure, Katherine is a slippery little fish, but we both know if I let you wander off you'll probably end up getting your pretty little neck snapped or something worse."
