Leave it to Claire to notice.
Although they had shared a handful of friendly conversations, Shannon wasn't ready to bare her soul to Claire Littleton. So when Claire followed Shannon through the jungle, her face bright with a joyful innocence the six-year-old Shannon hadn't possessed, Shannon was, in a word, pissed.
"Listen, I appreciate the help and all, but I've been taking a pee all by myself for years now. You can go back to Sharon or Karen or whatever you call that alien of yours."
"Aaron," Claire said brightly, catching up with Shannon. "He's a boy. Anyway, don't girls go to bathrooms in packs? Didn't you ever hide out in the bathroom with your girlfriends between classes, swapping lip glosses and gossiping about boys?"
"No," Shannon said flatly. She moved quickly, her long legs eating up the jungle floor. Despite her much shorter stride, Claire managed to stick by Shannon's side. Shannon twisted, Claire was right beside her. Shannon spun on her heel and took off into the jungle underbrush, Claire hunkered down and shimmied after her. Finally, Shannon stopped, glaring at the shorter woman. "Exactly what do you want?"
Claire shrugged happily. "I just thought you might like someone to talk to."
"You thought wrong," Shannon snapped. She crossed her arms over her chest and surveyed her surroundings. "Great, now I have absolutely no idea where I am."
"We're near the caves," Claire assured her. "We're just turned around a bit. You can see the back of Charlie's guitar case from here, see?" She pointed through the trees.
"Great. Fine. No need to see me back," Shannon said shortly. Annoyed, and not really knowing why, she tromped off away from the caves. She was desperate to be alone.
"Shannon!" Claire called to her retreating back. "I know."
"Keep it to yourself then," Shannon yelled over her shoulder. "You and Charlie are the only ones who are really pure enough to know." Shannon had absolutely no idea what she was talking about. All she knew was that she absolutely had to get away from perky, bubby Claire.
"I know about the baby," Claire called.
Shannon continued to stomp angrily through the jungle. "You have a baby. We've established that. Goodbye."
"I know you're pregnant," Claire said. Her voice, barely above a whisper, carried above the other jungle sounds.
Shannon froze. One second, fifteen, thirty, sixty….she didn't move. Slowly, she turned to face Claire. She scowled, tossed her perfect hair. "Trust you to figure it out. Now if you can just round me up the Morning After Pill, or Hell, even a coat hanger, I'll be a happy camper."
Claire tilted her head, reminding Shannon of a puppy struggling to understand her mistress's words. She placed one foot in front of the other, cautiously closing the gap between herself and Shannon. She didn't want to scare her away. "Listen, I understand this probably wasn't planned, but if you just talk to Sayid…"
"You little fool!" Shannon bellowed. Claire jumped back. "The baby isn't Sayid's! It's Boone's!" Shannon suddenly, violently threw her backpack at Claire. The heavy bundle hit Claire square in the chest. "I'm pregnant by my brother!"
