Here is my version of what could've happened in that infamous seduction scene between Chuck and Blair in 2.03

Ep. 2.03

Scene: Blair's party duiring the black out.

Blair: "I was thinking about Yale, but now I might transfer to Oxford..."

Chuck: "Ah..so much wasted potential..."

Blair: "What are you talking about?"

Chuck: "...Ah that's what's always had me fascinated about you. The cool exterior..the fire below..."

Blair: "You are living proof a person can't buy class."

Chuck: "You can't tell me Birtie Wooster is satisfying your needs. Titles aside, a suit of armor makes for a cold bedfellow."

Blair: "Not that its any of your business, but Marcus and I have an amazing sex life."

Chuck: "Is that so?..." [pausing for affect...leaning in closer] "What names does he call you when you make love?" [pulls her against him, with her back against his chest, stroking her from collarbone to hip] "Does he..?" (whispering in her ear) "I want to make love and watch you come for me?" [she rolls her eyes, clearly seduced] Have sex with me...just once that's all I need."

Blair: "You are disgusting..and I hate you!"

Chuck: (slyly chuckling) "Then why are you still holding my hand?"

Blair scampers off to Marcus and pleads to him...

Blair: "I need you now...meet me upstairs in my room."

Marcus: "I'd love to, but don't you have a party to host? We can't stand up our guests."

Blair: "Ooh meet me in ten minutes in my room."

Marcus: "All right, I'll see what I can do."

Meanwhile, Chuck hears Blair's proposition to Marcus and decides to get here first.

Blair has a single taper lit and when she sees a shadowy figure at her door, she asks...

Blair: "Marcus is that you?"

Chuck: (w/Ed's British accent) "Blow out your candle.."

Blair blows out her candle and Chuck comes to her and they kiss. Their kissing turns into firy passion in the dark, and they soon fall to the bed to further make out and begin to make love, with Chuck on top and Blair underneath. Their kisses unleashing the genuine hunger and passion that they have for each other, evident by even the little moans they make while kissing.

They don't notice when the lights turn on or anyone else enters the room, so intent they are on each other.

Marcus enters the room, aghast to see his girlfriend Blair, willingly pinned beneath the body of the young man who'd tried to seduce her earlier. the young man she's clearly still had feelings for, evident by the lover's embrace she is now tangled with him in. Still Marcus just sees red and initially goes over to the couple, pulls Chuck off of Blair (a sin if there ever was one), and gets into a fist fight with Chuck.

Blair: Marcus? Chuck? What are you doing?

Marcus: "I'm defending your honor from this vicious cad!"

Chuck: "I'm just proving that the early bird catches the worm."

Blair: "Oh good gracious! Unhand each other before you kill one another, you two."

Marcus: "Defend him? I should have known."

Chuck: "Well I can't help it, if timing is everything and your timing just ran out."

Blair: "Oh you two."

Marcus: "So who do you want to be with, me or him?"

Chuck: "Yes Blair, which one of us do you want to warm your bed? A cold suit of armor...or a lover who knows you better than anyone alive and keeps you coming back for more time and time again?" (he seductively mused)

Blair: "I...can't decide!"

Marcus: "Then let's settle this like gentlemen. I thrown down my gauntlet and challenge you to a duel!" (as he threw down his glove)

Blair: "A duel?"

Chuck: "A duel? Very intriguing...Pistols or swords?"

Marcus: "I do not know your level of swordsmanship sir, so to not be at an unncessary advantage, I would say...Pistols at dawn on the Sheep Meadow of Central Park, tomorrow!"

Chuck: "Excellent! I will accept your challenge, may the best man win."

Blair: "Oh no!"

The next morning not only are Marcus and Chuck on the Sheep Meadow, with the early morning fog rolling over the clipped grass, but Blair shows up too to watch the proceedings. Blair approaches Chuck, clearly upset, as he lifts an antique dueling pistol from a wooden case that Nate is holding open for him.

Blair: "Chuck, I can't believe you're going all Alexander Hamilton and Aaron Burr on me by going through with this!"

Chuck: "He challenged me to a duel for your honor. It was too tempting to resist."

Blair: "But pistols at dawn?"

Chuck: "Yes, Nate was kind enough to let me use his great grandfather Vander Bilt's antique dueling pistols, if I let him be my second."

Blair: "18th century dueling pistols...and Nate Archibald as your second? You could get killed!"

Chuck: "Ah it warms the cockles of my heart to know that you care! But what about him over there?" (he said gesturing toward Marcus)

Blair: "Well he could too!"

Chuck: "Ah...well I guess there are some things that have to be done."

Chuck marched off to set his pace, while Nate allowed Marcus to choose the other pistol.

The two men marked off twenty paces, turned, aimed and fired. The guns made a lot of noise and smoke, and Blair screamed, nearly fainting. When the smoke cleared, both men were still standing, however before either could do anything, two police officers come to arrest the two men for illegally dueling in a public place. Blair ran to Chuck noticing he might be hurt, but when she approached him, he winked at her.

Blair: "Oh Chuck, are you injured? I can't believe I let it go this far!"

Chuck: "Ah you do care...but it's only a flesh wound...see" he whispers as he shows Blair his fake wound.

Blair: "Fake? Chuck Bass what sort of scheme are you playing this time? You know you're going to get arrested for setting off a firearm in a public place."

Chuck: "I know, but for me it's a slap on the wrist. However Marcus may find it a bit more difficult convincing the British counsel that he's that innocent...when its deportation time!"

Blair: "Chuck...you're bad!"

Chuck: "I know..and that's why you love me. They say all's fair in love and war...and when it comes to loving you, I'm always up for a challenge. So tonight do you want to meet me at my suite?"

Blair: "After this, what do you think? Still what if your dad doesn't pay your bail right away?"

Chuck: "Well have you ever heard of conjugal visits?"

Fade out as Blair laughs and assists Chuck to the police cruiser.
