A/N: This is a continual of 6x02 and I'm thinking of updating this with missing and extra scenes from the new episodes, all revolving around Mark and Lexie of course. I think it'd be easier this way rather than uploading a lot of separate one-shots. I hope people will be interested in this. Anyway, as always, let me know what you think! (:

When he comes out of the shower, dressed in a grey T-Shirt and low ridding jeans, he sees Lexie standing in the middle of the room, her back to him as she stares at the door. Moving so that he stands next to her, he tilts his head to one side as he considers her thoughtful expression.

"Lex?" He says cautiously, unsure of what exactly she is doing. When she doesn't show any signs of acknowledging him, he frowns and says, "What's wrong?"

It is then that she snaps out of her daze and looks up at him, her face momentarily showing her surprise. She then shakes her head gently and bites her lip. "I, er…" She trails off before quietly saying, "Nothing."

Mark doesn't say anything at first but then something finally registers in his mind and he states, "You have that look on your face."

"I don't know what you're talking about."

Her reply is rushed and defensive, the words tumbling out causing Mark to realize that his suspicions are right. She has done something. Crossing his arms over his chest, he gives her a stern look as he asks, "What did you do?"

Huffing slightly, Lexie shoots him a look. "Isn't that supposed to be my line?"

"Usually, but for once I'm not the guilty one." He smirks when he adds, "You are."

Suddenly flustered, Lexie jerks forward and stammers, "I, er, I should go."

Before she gets too far, Mark reaches out and his hand on her arm stops her movements. Moving closer to her so that his large body loomed over her, he murmurs, "Stay." He rubs her arm gently, knowing that it always made her give in, and says quietly, "Talk."

Lexie lets out a sigh before she turns to face him. She doesn't move away from his touch when she states, "She's gay."

Mark looks at her for a moment, originally confused, until it clicks in his mind. Callie. "Right…"

Lexie rolls her eyes and suddenly she feels angry and so lets out an aggravated sigh when she begins, "Sh-She's gay and, and I know you don't see her in that way because you, you don't look at her boobs anymore and I should believe her because she did tell me and it sounds true and you know, it's good that you don't look at her boobs anymore, that's good, that's good but I, er…" Lexie pauses and takes a deep breath, her eyes wide as she mumbles dejectedly, "It's not good."

"Not good," Mark repeats after a moment, his hand moving away from her. He crosses his arms over his chest as he watches her and then slowly asks, "Are you saying…you want me to look at her boobs?"

"No!" Lexie shrieks, her eyes wide as she turns to face him. "No! God, no!"

It is hard to hide his smirk when he says, "Because I will you know, if that's what you want."

The looks she gives him is enough to kill. "Shut up."

"No, really." Mark leans in slightly, and licks his lips. "If my girlfriend's telling me to stare at my friend's breasts then who am I to deny her wishes?"

Although she tries to pout, there is a small smile quirking the corners of Lexie's mouth. She glares at him and mutters, "I hate you."

Mark shoots her a grin and then places his hands on her shoulders. "Come on, Lex." He moves his hand down to grip hers and slowly moves her so that they can sit on the couch. Still holding her hand, he looks at her and looks at her sternly. "Now, tell me exactly what's wrong."

There is a brief silence before Lexie sighs and looks at him, her expression dejected as she shrugs. "She's beautiful."

Mark nods in agreement before he reminds her, "And gay."

An annoyed grunt escapes her lips and Lexie rolls her eyes. She removes her hand from Mark's and crosses her arms over her chest. "Supposedly," she mutters.

"You don't think she's gay?"

Lexie's arms suddenly go flying as she half-shouts, "Well, she wasn't gay last year!"

Suppressing his smile, Mark tries to look serious as he nods and says, "Right."

Picking up on his tone, Lexie realizes that he is trying hard not to laugh at her and rolls her eyes as she sighs. "I'm being stupid, aren't I?"

"Yes." When she sighs again, he smiles gently and wraps an arm around her shoulders. He leans in slightly as he murmurs, "And crazy and irrational."

"I know! I know but…" Lexie trails off as she lowers her gaze, unsure of whether or not she should voice her concerns. He wasn't going to take her seriously. He would merely brush her off, telling her she shouldn't think like this. Lexie knows this but she can't help these thoughts. How could he not realize how much pressure she was under? Compared to all his previous conquests she was simple and nothing special. Unlike Callie.

Lexie looks down at her feet as she reluctantly says, "She's beautiful and, and I'm not."

His heart clenches at her words and he hugs her tighter. "Lex…"

"She's curvy and busty and tanned and, and what am I?" Lexie feels tears prick her eyes as she raises her arms in annoyance and then lets them fall to her sides. She shakes her head as she shakily says, "I'm short and mousy and pale and I'm not glamorous. I'm not exotic or exciting. I'm, I'm simple. And plain. And, and, I'm nothing compared to her."

Mark looks at her, unblinking and for a moment, what she says doesn't register because he can't quite understand what she is saying. The words make sense, it all makes sense, but he doesn't understand, why Lexie, his beautiful, amazing, special, unique Lexie, was saying that she was nothing. That she was not worth anything next to the others he had been with.

He stares at her and frowns. Had she hit her head without him knowing? It was the only thing he could think of that would explain her words because she was acting crazy.

Mark narrows his eyes at her and slowly asks, "Did you hit your head today? Because that's the stupidest thing I've ever heard."

At first Lexie doesn't know how to reply before she frowns at him and grumbles, "You have to say that. It's your job."

"It's the truth."

"Right."

His stare is steady on her as he states, "I wouldn't say something if I didn't have to. You know that."

"And yet I don't believe you."

Rolling his eyes slightly, he takes her hand and brings it up to his lips. Softly kissing her skin, he looks up at her and notices her initial surprise. Smirking slightly, he kisses her again and then speaks softly against her skin. "I don't look at her like that anymore." He kisses her again, his gaze steady on hers. "That's why it didn't occur to me to tell you that she lives across the hall. Because I don't look at her like that anymore."

Feeling his lips on her, so delicate and right, Lexie knows she should believe him. She knows she shouldn't act in this way and that he was right, she was being irrational about this, but the voice was still there, at the back of her mind, reminding her that this wouldn't last. He wouldn't settle for a woman like her.

Lexie sighs and looks away, her eyes lowered as she tries to explain. "But she's so…" Lexie breaks off, unable to say the endless list of adjectives to explain the beauty of Callie Torres. It hurt too much to think of it, let alone say it. She sighs again, "And, and I'm just…not."

"Okay, that's it."

Suddenly, Mark grips her shoulders and moves her so that she was staring directly at him. With their knees touching and Lexie's heart racing under his intense gaze, Mark's voice is deep and rough and perfect as he states, "I love you. I love you. Yes, I was attracted to her but that's in the past. I never loved her, Lex." When Lexie's eyes look down, he moves closer to her and places a soft kiss on her lips. Slowly, to his relief, she looks up at him, her eyes doe eyed and it is enough to help the words spring out of him.

"I think you're beautiful," he says, his voice rough as his hand moves from her shoulder to touch her exposed neck. "Everything about you is beautiful." His eyes trace over her and he gently places a kiss on her cheek. "Your mind, your face, your body, your heart, your work, everything about you is beautiful." Suddenly, he kisses her again, this time deeper and when he breaks away, he whispers, "You're so beautiful and…You amaze me, Lex. It amazes me that you would even want to be near me."

Slightly shaken with emotion, Lexie smiles gently and although she still has her doubts, they had now been pushed down into a dark, tiny corner of her mind. She wouldn't think about it, not now. Now, she had Mark and that was all that mattered. He was here and he wanted her.

Lexie smiles as she moves closer and gently kisses him. With her hands on either side of his face, she lets her lips rest on his as she whispers, "I love you, too."

Her words make him grin and suddenly he is chuckling, the idea surprisingly funny. "This is crazy."

Lexie's smile matches his and she laughs as well, the sound brightening the room. "I know."

Taking her hand in his, he kisses it again and although he tries to sound confident, a touch of uncertainty slips into his words, "But it's true."

Instead of replying, Lexie grins and launches herself at him and her hug and soft kisses against his neck is enough to convince him. Mark lets out a sigh of relief and hugs her back, unwilling to let her go. Despite all their insecurities, this is what they wanted. This is what they had fought hard for and there was nothing that could tear them apart now.

He would never let her go.

You may fall but I swear that I'll help you believe.
