Having changed into her usual black utilitarian outfit –oh, like coming home—Shaw retrieved Root's Taser from her bag and tucked it in one of her cargo pockets. She slipped out of the hotel and debated whether to take the city bus or a taxi downtown. Taxi. Faster. She stepped forward on the street to hail one.

The taxi pulled up to the Frisco Bar, and Shaw stared at it. It was obviously a local watering hole, and she'd look out of place with her clothes. Bloody hell. Root's imaginary voice mocked her "See, Sameen, you need to conform to society's idea of clothing sometimes." Shaw looked around and spotted a nearby plaza that was well lighted and still had people milling around. Perfect. She found a cart that sold clothes, but they were all dresses. Shaw inwardly groaned as she selected a flowery Mexican sundress and the old woman nodded her approval as she rang up the purchase. Shaw grouchily grabbed the dress and sandals from the old woman and stalked off to find a dark alley to change.

The door to the bar opened, and Shaw scanned the room looking for a place to sit and take stock of her surroundings. Perfect. There was an open seat at the bar and she sashayed up. "Tecate, por favor." "Certainamente, senorita," replied the bartender, pushing a ice-cold Tecate in front of Shaw. Shaw tilted her head back and took a hearty swig. That fucking hit the spot.

Setting the beer bottle back onto the counter, Shaw looked around. There were all sizes and shapes of Mexican gentlemen here, from the construction laborers to the service industry guys. Scanning the men's (and occasional woman's) faces, Shaw wondered if this bar was a dead end. Suddenly, the door leading to the banos opened and out came Luis Allende. Shaw narrowed her eyes at the perp. He was fucking going to get his due.

As Luis drew nearer to where Shaw was sitting, she noticed something off about his walk. Suspicion warring with anger, she held herself back as he passed her. What? Luis was sporting strange bruises and she'd wager that under his clothes were more. Eyebrows drawn in puzzlement, Shaw sat back and took stock of the situation. Root didn't even have a chance when this guy struck at her, and Hayden was just a victim, so it couldn't have been her. What the hell was going on?

As she nursed her beer, watching Luis down three to her one, her unease grew. Luis' demeanor was one of a sad, maybe broken, man. He certainly didn't look like he had just roofied an American in hopes of getting into her drawers nor gone so low as to hit a "defenseless" –ha!- girl from behind. Hayden was right. It wasn't him. If not Luis, then who?

Shaw decided there and then to follow Luis to whatever shithole he slept at. Should she stalk him or do it the easy way? The easy way.

They left hand in hand, laughing. Luis stumbled a bit as he was feeling the effects of five beers. Shaw played along, giggling at him –I never giggle—and looking up at him with an adoring smile. Luis smiled down at her and held her hand as they wandered the dimly lit streets towards his home. As they neared, though, Luis suddenly stopped. "I am sorry, sweet senorita, but this cannot be." Shaw, puzzled, replied "Por que?" "My sister… she is not in the best of health," Luis said nervously. Shaw pouted and said "We could sneak past your sister, couldn't we?" Luis's face was serious as he looked down at Shaw and mumbled, "She is sick in the soul. I would not risk your face, mi bella, for my sister to claw and ruin."

Sister? Shaw persisted, "Has she done harm to others before?" Luis' eyes held a world of sadness as he quietly mouthed "yes". Shaw looked up at him, at a momentary loss for words, when she noticed a face in the window of Luis' house peering out at them. She barely had time to register the face when the same face came running out of the front door, shrieking like a banshee. Luis whirled around, dismay on his face. "Nada, Maria! Nada! She is my amiga! Do not harm her!"

Maria fell on him, shrieking and pounding him with her fists. Shaw stood there, dumbstruck. The look of rage on Maria's face was… she was truly too far gone for help. She was insane. Luis held his arms over his face, waiting for Maria to pummel away her rage; better him than the beautiful senorita whose smile had captivated him for the evening. Shaw then realized that Root's Taser was hidden beneath her dress and she reached for it. Circling slowly behind Maria, she activated the Taser and shocked Maria with it. Maria fell to the ground, rage still convulsing her features. Then she was still.

Luis gaped at her. "Senorita… how do you come to have that with you?" "Let's just say I walk in not-so-nice areas upon occasion". Both of them looked down at the slack-jawed Maria, and Shaw broke the silence "I… you know, I have some doctor experience. Your sister… she needs help." "Don't you think I know it? There's nothing out here for her. And I can't get her into the States much less pay for her treatment" Luis said angrily.

Shaw was left unsure what to do. Maria obviously had been following Luis' movements all evening and was the one that fed roofies to Hayden and struck Root from behind. Ordinarily, she'd feel no guilt by kneecapping the perp, but Maria's situation was different.

"Luis… Maria hurt Hayden."

Luis stared at her in shock. "No, that's not possible. How…" Shaw knelt down next to Maria and examined her pockets. She drew out a bottle, that upon opening, showed GHB. "I'm afraid so. Hayden was drugged and she passed out on the dance floor." Luis turned, hands on his heads and obviously distressed. "Why did you leave the dance floor? Everybody thought you'd done it because you brought her drinks all night."

"I left because… Maria found me in the bano and attacked me. That's why…" he indicated the bruises on his face and elsewhere. "You're right. Maria obviously slipped this… drug… in one of the drinks I brought Hayden. Is she all right?"

Shaw nodded and Luis heaved a sigh of relief. Shaw thought about it and made a proposal that Luis couldn't turn down.

"They're not virgin this time," smirked Root as she brought over two strawberry daiquiris to where Shaw was lounging. Shaw rolled her eyes as she took a sip. "What did Finch say about our travel arrangements?"

"Oh, Harold said that he couldn't get us back to New York until after the weekend since the flights are all filled up with the spring breakers returning home. He also got us a room here at this hotel so we could enjoy the beach… among other things." Root waggled her eyebrows and Shaw's eyes narrowed. "So you're saying we're stuck here for another two days?" "Yes, dear" purred Root.

Shaw sighed and looked around. Maybe some downtime wouldn't be so bad. Her gaze settled on the crowd of college kids in the pool and found Hayden among them. Earlier this morning, when Shaw had explained to Hayden what was going on with Luis' sister, Hayden was so relieved that her instincts were right about Luis not being the perp. Shaw wondered if Luis would come see Hayden before she returned home. At least Luis' sister would receive treatment at a Houston facility, paid for courtesy of Finch. She shook her head, wondering why she cared- she really didn't. Number was safe, her job was done, and that's that.

Shaw was starting to feel the effects of the heat, and when she heard a splash!, she turned her head to find Root in the pool, gliding sleeky through the water. That's a good idea and Shaw got up to join Root in the pool. Root swam towards the throng of college kids and as she slowed in order not to hit anyone, she heard a yell "Hey Grandma! Whatcha doing here?" Root's mouth dropped open in a 'O' of surprise… definitely not expecting to be called a grandma of all things. Even worse, she could hear Shaw sniggering behind her back. Root turned her head to locate the heckler and the heckler was laughing with his college buddies. If I can find out what your name is, you're so dead thought Root threateningly. As the heckler continued to laugh his asshole laugh, Root opened her mouth, prepared to say something scathing in return until she heard "Well, she may be a grandma to you, but let me tell you one thing—she's a fucking hot grandma which is more than you could say for yourself." Root looked to her left, startled, and Shaw was glaring at the heckler with her patented Shaw stare which effectively quieted the heckler. Shaw then looked at Root and spit out "Let's get out of here." Root couldn't stop smiling as she followed Shaw out of the pool and towards the elevator.

Dripping wet, they rode the elevator in silence until "Thank you" came from Root. Shaw looked at her and replied "I meant what I said." Root's breath caught and their eyes locked. Shaw groaned and jammed Root up against the wall. "If we do this… this stays in Cancun. No mention of Cancun ever. Do you understand?" Root smiled and murmured "Fine. Your rules, Sameen. But if you break your own rules, all bets are off." Shaw's eyebrows furrowed as she considered that but as her gaze dropped to Root's lips, all rational thought flew out the window and their lips met furiously.

They somehow managed to make it from the elevator to their room, and Shaw pushed Root down on the bed. She took in the delicious sight of Root, uncertainity showing on her face, her rapid breathing heaving her chest up and down, the nipples visibly erect under that damn red bikini. Shaw felt a rush of lust unfurling in her belly now that this was really going to happen.

Shaw remained where she was, eyes roving over Root's body. She reached behind her back to unclip her sport bikini top, the one Root found so ugly. Root watched as the top slipped free and the curves of Shaw's breasts were revealed. She felt her excitement building with the combination of Shaw unveiling herself and maintaining the charged eye contact between them. Shaw started touching herself, gently circling her nipples and tweaking them until they angrily stood out. Root felt the heat build up in her belly and moaned. "Sameen… touch me." "No." Root looked at Shaw, startled. "You said you'd touch yourself if I didn't stop." Shaw's eyes were now heavy lidded as she continued fondling her breasts.

Root's hand rose up and slid straight to her pussy. She made light circles over the crotch of the red bikini, then allowed her hand to slide inside and her fingers danced over her clit. Root parted her legs slightly to allow herself better access, and let a moan slip out.

"Take off your bottom."

"No. You want it gone, you take it off yourself." gasped out Root as her hand made faster and faster circles. God, seeing Sameen look at her like that, with lust, was a real turn-on.

Shaw hissed and Root felt the bed sag as Shaw knelt on the bed. She felt her bottom slip off and her gaze followed it as Shaw threw it across the room. Shaw was now kneeling between her legs and Root's fingers were now teasing the slick entrance to her cunt. As Shaw watched, her own hand slipped down to her bottom and under it. Root moaned at the sight of Shaw fingering herself in tune to Root's motions. She so wanted that bottom gone and voiced her demand. "Come get it." Root growled and came up so fast she was able to flip Shaw onto the bottom before Shaw realized what was happening. Straddling Shaw, Root breathed "You're such a bad girl. I'm going to punish you now."

Shaw's hands came up to grab Root's breasts, still hidden beneath her bikini. Shaw slipped down the top so Root's breasts swayed free and Root could barely contain the moan that threatened to slip out as Shaw's hands toyed with her. Every electrifying pinch and roll seemed to travel directly down to her belly and Root started rolling her hips, grinding against Shaw. Damn. Her bottom was still in the way and Root lowered her head, trailing her lips across Shaw's abdomen until it hit the edge of Shaw's bikini bottom. Taking it in her teeth, Root dragged it down until it slipped off Shaw's hips. Such beautiful curls, thought Root as her mouth descended down into them. Shaw's hips bucked as Root took her clit into her mouth and alternated licking and sucking. Root slid a finger up and down Shaw's now very slippery slit until she found the entrance. Making teasing circles around the entrance, but refusing to slide it in entirely, she heard Shaw let out a groan of frustration. "Didn't I say you were a bad girl? See what happens when you don't listen."

"Root…" pleaded Shaw. She needed that finger in her right now.

Root smiled teasingly, as her finger continued to tease the entrance and then pressed her thumb against Shaw's clit. "God, Root. Now!" Root's resolve broke at the sound of Shaw's desire-fueled voice and she plunged her finger inside, thrusting as hard as she could. Shaw writhed under her and Root added a second finger. Root then positioned herself against her two fingers that were driving in and out, and began a fucking motion. She watched lustily as her hips drove her fingers in and out of Sameen, and the sight of her legs writhing and bucking drove Root closer to the edge. She could see that Sameen was close, too, and so she slid her fingers out and lifted one leg over Shaw's so their pussies ground together. Root was lost in the grinding motion, trying to finish, when she felt Sameen's hand slide in between them and start to stimulate her clit. Root gasped and felt everything that had built up start to come together, and her orgasm was blinding. She heard Shaw grunt as she came at the same time.

Laying on top of Shaw, still breathing hard, Root lifted her head and looked directly into Shaw's eyes. They were still heavy-lidded and sensual. "See… told you we'd be good together" said Root in a self-satisfied voice. "Wanna try the shower next?" Shaw's mouth curved into a half-smile.

The plane landed at LaGuardia, and Root and Shaw were picked up by Fusco as to avoid the cameras under Samartian's domain.

"You ladies have a good time?" snickered Fusco.

Shaw shrugged. "It was okay." She glanced at Root who smiled wryly. "But Grandma over there apparently enjoyed herself." And Shaw couldn't help herself, she snickered a bit. Fusco gave them a puzzled look in the rearview mirror and knew it was some sort of inside joke he'd never understand.

Shaw glanced at Root as the car pulled away. Root had that damn smirk on, and Shaw knew that spelled trouble. "Spill it, Root. What's that smirk for?"

"You broke the rules, Sameen." Root's smirk grew wider, transforming into a full-blown grin. Root leaned over and whispered, "Isn't 'Grandma' part of the weekend-not-to-be-mentioned?"

Oh shit.

Shaw shook her head and closed her eyes, leaning her head back on the headrest.

Root looked out the window, smiling. Cancum, indeed.
