A/N: So this chapter was a bit hard to write, I don't see Thane being like this at all. But when I read the comics about him, he was a completely different person. Of course, that could be because it's set in somewhat different times to this story. But I imagine Thane can be very possessive of the things he cares about and well, Drell are different to humans. Just trust the process with this, it won't be as we'd expect it's going to go.

Shepard had been ignoring Thane for over a week, helping the crew instead with their personal issues. She had been struggling to sleep for many days and her nightmares had been worse. She needed someone to talk to, but Thane was all she had before he shut her out.

Thane was just as bad, his meditations were not helping and he slipped into memories about Shepard more frequently. Chakwas had noticed his sudden change in mood and asked to see him. Thane didn't want to see the doctor, but keeping regular appointments with his disease was important towards the mission.

"Ah, Thane, come in," Chakwas says with a soft voice. He bows and takes a seat on the end of the bed she motioned to. The med-bay was definitely state of the art, just as Shepard told him, maybe the doctor could be of some help to him.

Thane got comfortable and let Chakwas start her scans of mostly his chest, she made him do a breath test and made grunted noises to herself as she typed on the datapad. "Well, your lungs have not changed much, but I see your oxygen intake has dropped slightly. Have you been stressed?"

Thane didn't even need to tell her without his expression saying he was in fact very stressed. Chakwas knew there was something odd between him and Shepard, but neither wanted to admit it of course. "Look, Thane. This is not my business, but you should know Shepard is not doing so well herself either, you both are very stressed and are actively ignoring each other."

"What is wrong with Shepard?" Thane asked with some concern, he hadn't even seen her for the last two days. She had been asking Edi where he was in the ship so she could get around her own ship without seeing him. He knew he had truly hurt her, but it was to protect her... things between them both could not go any further.

"I cannot go into detail but she struggles to sleep and shows very high levels of stress, she has not been seeking help and will not take medication to sleep." Chakwas had been getting Edi to track Shepard's sleeping pattern, out of the last full week she had maybe slept four to five hours for every two days that passed. Stims and food were the only things that kept her going during missions.

Thane got off the bed, he knew he needed to fix this. He was going to talk to her and just explain himself and ask for forgiveness, nothing else can happen from there. "I must go," he says with haste and leaves the medbay, Chakwas only could hope he was going to do the right thing.

"Edi," Thane called the AI. Edi soon appeared on the terminal by the lift. "Where is Shepard?" Edi paused for a moment before answering.

"She is currently having a nightmare in her cabin, I believe she is crying." Thane took off running, he slammed his hand against the lift to the loft and tapped his foot as he waited for the lift to slowly ascend.

The lift doors opened and he walked through the small hallway to her cabin door, it was glowing red. He hacked the door, knowing it was against his Commander's wishes, but he had to do this. Edi seemed to understand as she didn't try to stop him.

The sight inside was heartbreaking for him, he found Shepard rolling in her bed, shivering and screaming as she pulled at her covers and laid in her own sweat. "Shepard?" he whispered as he walked down the stairs, his eyes nearly drifting to the fish in her tank. She didn't respond, but another scream left her lips. "Shepard," he said again with more urgency.

He shook her a bit and her eyes snapped up. She nearly punched him in the face with the pistol under her pillow, but he was able to deflect it and catch the barrel of the gun. "Get out," she cried, her eyes struggling to get the vision of who was sitting on the bed beside her.

"It's Thane. You were having a nightmare, are you okay?" Shepard finally saw the Drell as he looked at her with worry, she scoffed at him and got up. "Wait, Shepard," he pleaded.

"What do you want? You're the reason I'm fucking like this," she shouted as she tried to walk up the stairs to her bathroom. Thane pulled her arm and kept it in a tight hold she couldn't get away from.

"I need to explain myself to you," he sternly says. Something glassed over his eyes, she noticed it as his usual calm and collected self turned almost possessive over her. Shepard narrowed her eyes and nearly hissed at him.

"Fuck off, Thane. I don't need you okay, you aren't who I thought you were," she shouted. She had just been able to get up the stairs, pulling him along with her. Thane growled and slammed her up against the tank. Even though it hurt, her body became near hot with lust for him, she mentally shouted at herself for her body giving it away.

"You don't know me enough to know that," he says in a deep, husky voice. Shepard felt herself getting wet by just the sound of his voice, she felt his warm breath over her face. "Will you listen to me, or will this be the way I must show you?"

"The hell are you talking about?" Thane slammed his lips into hers, letting her body melt into his. He kept both her hands bound tightly together above her head and used his free hand to pull at her tight alliance shorts. "Thane," she says as she pulls away. "This is not what I want with you, not anymore."

"So why does your body tell me a different story? I can smell your desire for me." He licked her chin and neck, she moaned and craned her head back against the tank. "I will show you myself," he whispered as he dropped his hands into her pants and glided his fingers over her wet folds.

Shepard was able to get one hand free and touched his frills, he growled and slammed her back into the tank. She gasped as he started to finger her, she nearly doubled over at the pace he went. Shepard's thoughts were flying everywhere, she never expected this from him.

He pulled his finger out just before she could come and her sad moan made him smirk. Shepard broke both her hands free and fought with his leather pants, he let her do so as she bent down and kissed his thighs. He let her study his hard member, she didn't know what to expect from him.

The main thing that stood out was Thane's dick had ridges and it was noticeably bigger than a normal human male. She shook her head, remembering he wasn't human. Thane pulled her back up and pulled her over to the desk, she sat down on it and Thane barely let her get comfortable before he pushed himself into her and started fucking her.

"Jesus, Thane. Slow down," she moaned, it hurt but she was able to adjust quickly enough. Thane growled into her neck and bit down on her neck. Shepard felt his teeth leave a mark, but also something went inside her neck. Then she remembered from the datapads, the venom.

Her lust for him became even hotter as his venom coursed through her body. "You're so different," he muttered into her ear as he picked up the pace. Shepard wrapped her legs around his waist, leaning back and letting all her datapads and belongings fall from the desk.

Garrus and Tali had been having lunch together when their conversation had turned to Shepard and her behaviour. Chakwas came out from the medbay to get some coffee when she overheard them talking about Shepard and then the mention of Thane.

"Thane seems to understand the issue with Shepard," she comments. Garrus looks at her then back at Tali.

"Where are they both? Edi?" Edi popped up on the kitchen terminal.

"Thane is currently with Shepard in her cabin." Tali giggled with some excitement, she knew that could only mean one thing.

"What are they doing?" Garrus asked, tapping his talon on the table. Chakwas was somewhat curious as well. The AI just pulsed her blue and didn't reply straight away.

"I am sorry, Garrus, but I cannot disclose that at this moment, logging you out." Chakwas looked at Garrus with her mouth open wide in shock.

"I did not expect this, if it is what we think," Chakwas mutters as she goes back to the medbay. She needed to know if Drell and human sex is something that can cause issues, but first, she must wait to find out if that is what is actually happening.

"He better not hurt her," Garrus grumbled. Tali nodded, she was still in shock. Edi definitely knew what was going on, she just hoped Shepard's cabin wasn't bugged.

Thane had pumped himself one last time into her before filling himself with her wetness contracting against the ridge of his dick. Shepard had screamed his name as she orgasmed another two times during their time on the desk. Thane then froze, he felt his chest tighten, but not with breathing problems. This wasn't right, he'd just used his Commander.

"You okay?" she breaths as she rests her forehead against his. Thane pulls away, pulling himself from her and bringing his leather pants back into place. Shepard got down from the desk, feeling what he'd left inside her drip down her leg. The venom hadn't affected her so much, her cybernetics seem to have gotten rid of it quickly enough.

"I must go," he says with a low voice and turns to leave. Shepard felt her world come crashing down, she grabbed the back of his leather jacket and pulled him back.

"Don't you dare," she cried out. "I just gave myself to you, what am I? A pity fuck?" Thane bit his lips, he pushed her hand away and walked out. Shepard stood by the desk feeling her legs shake. She just fucked a Drell that hurt her once and he's just done it again but ten times worse.

Shepard went to the shower turning the water to the hottest setting as she sat on the floor of it and cried into her knees. She felt so full and complete with him, and now just as lonely as when she lost her whole family on Mindoir.

Thane got out of the lift and went to the kitchen to grab some water. Garrus and Tali were still in there, Garrus instantly shot his head up and watched as Thane grabbed his water and scurred to lift support.

"Oh, he better not have," Garrus grumbled as he slammed his drink down and got up. Tali watched him as he kicked the chair away.

"What's wrong?" she asked, she saw Thane herself, but she didn't get why Garrus was so upset.

"He fucked her, I can smell it. He left her straight after, I will kill him!" Tali stopped him, pulled his talon to come back to the table. He tried to pull away, but she stood up and got in front of him.

"You don't know that, Garrus. Shepard might have kicked him out, give them some space. We can't get in the way of whatever is happening." Garrus looked at the floor, his mandibles so tight to his face he thought it might cut his cheek plates.

"If you're wrong, he's dead," he says as he storms off to the main battery. Tali only hoped she was right, she wanted to see Shepard but knew they needed space. She decided to return to engineering.

Thane sat at the table, his hands shaking as he recalled the memory for the second he kissed her to the moment he emptied himself into her. How was he meant to tell her? From what he experienced it had made this situation so much harder to deal with and she'd hate him even more now.

A/N: Well now I see Thane in a much darker light, but this will make sense soon. Till next time :)
