Sheppard finally lets go of her in a deep pit of a room, filled with some old dead consoles and tables. The lower door is sealed shut, rusted by the ocean water, and there's only one dim wall sconce illuminating the space. Everything has that pale green-grey look indicating the room had been previously flooded; a section of the ceiling had collapsed and been washed away. That's how they got in, Sheppard dropping down from the level above and pretty much just pulling her down with him.
The landing had jarred her legs something nasty and knocked the wind out of her for a bit. The only way out was back through the hole in the ceiling. She could climb out, but there's no chance with Sheppard around. After dropping her in the far corner of the room he scales the wall and back up through the gap like it's nothing and briefly disappears. She barely has time to drag herself upright, recover her breath, and take a look around before he's back on top of her, invading her personal space.
He's all over her, intimidating her, hissing and pawing and growling. She tries to back away, shove him off, yell at him to leave her alone but nothing seems to help. Eventually he pins her against a wall, one arm twisted behind her back. She freezes again as he presses himself up against her back, his face right up next to hers. More sniffing, maybe? Instead, Sheppard's tongue darts out and he licks the blood off the side of her face, from her chin up to her temple.
She officially goes from scared and creeped out to downright terrified and grossed out, but at the same time the scientist in her is fascinated by his behaviour. She can't help it - she's a Xenobiologist. Her mind automatically categorises and analyses his actions. Every attempt at fighting back or getting away has just gotten her more hurt, and made Sheppard more angry.
He's sniffed her, pinned her, dragged her around. He doesn't seem to be interested in killing her, but he has no problem with hurting her. He's abducted her away to somewhere secluded and dark. They're alone. Oh crap. They're alone, far away from everyone, and now he's tasting her. Pinned to the wall, she theorises that his actions are that of an alpha male trying to assert his control, to show dominance over her. Hopefully that's all it is. They don't know much about the Iratus bugs... actually, they don't know anything other than their feeding similarity to the Wraith, so she can only speculate as she observes.
As she stands there, frozen, Sheppard rubs his inner arm and the underside of his chin against her in various places. She twitches, and he hisses viciously in her ear. Yep. His behaviour leads her back to the same conclusion. If she fights or tries to run, he'll hurt her more, and it will probably kill her. Or… or she can submit to his dominance. She's not sure where that will lead (she has an idea, a bad idea), but she definitely doesn't want to die so the logical, scientific part of her makes the decision: she submits. But how can she show her submission, pinned up against a wall, unable to move? He clearly isn't listening to words any more, isn't lucid in the human sense. Not human. Animal. Oh! She desperately latches onto the concept.
She forces herself to relax in his grip, and, for lack of a better option, (she can't twist or move far enough to bow or show her stomach) she tilts her head sideways, up and back, exposing her throat to him. Slowly, he releases his tight grip on her twisted arm, and leans into her throat, sniffing her again and rubbing his chin up and down her throat. She holds herself still, even when he nips her neck to test her submission. His clawed hands are dangerously sharp and long and very near her throat.
He eventually bites down, quite hard, on her shoulder near her neck, and she yelps, but remembers just in time not to pull away. He doesn't break skin, thankfully, but it's another source of pain on top of her already throbbing temple, bruised cheek, split lip, bruised arms and legs, and likely sprained wrist. If it weren't for the solid rubber of her watertight dungarees she would probably have lost the skin on her shins and knees by now too.
A few tense, painful seconds pass before Sheppard is satisfied that she's truly submitted to him. He lets her go and turns away, and she slumps to the floor, leaning forward to rest her forehead against the wall. The relief, the hope, is short-lived when less than a minute later Sheppard turns back, hauls her up by the throat, spins her around and yanks at her dungarees. He's staring her straight in the eyes, and he hisses and yanks again, his long claws ripping a vertical gash through the rubber suit over her stomach. She knows, then and there, that Sheppard intends to have her.
It's in line with the behaviour he's been exhibiting, even if she had hoped it wouldn't actually happen. But it is, and she knows she has no choice but to submit if she wants to survive. Not breaking eye contact from his intense stare, she lifts her shaking arms to unclip the rubber dungarees she was wearing and they slide off. Moving carefully and slowly, she steps out of them, now barefoot, and unfastens the button on the swimming shorts she had been wearing underneath.
Before she can take them off, Sheppard is yanking them and her underwear down, and they end up on the floor as he drags her partly across the room, spins her around again, and bends her over one of the tables. Her instinctive flailing earn her a head-slam into the tabletop and her already sprained left arm is twisted up behind her back. Sheppard claims her, then, and her hips, thighs and stomach are set afire as she gets slammed into the edge of the table repeatedly.
His grip on her wrist is agony but crying out seems to make him angrier, rougher. She covers her mouth with her right hand, scrunches her eyes shut, and remembers to just breathe, breathe, breathe. She can't help it, the pain grows and eventually a scream escapes; It's rewarded by a sickening crack from her pinned left arm as Sheppard crushes it with his grip. The pain from the break floods her mind, combining with all the other hurt, and rapidly overwhelms her.
She feels Sheppard slamming her into the table one more time before the darkness takes her away.
