A/N: okay I basically was watching a Doctor Who Confidential and The Wedding of River Song at the same time, and this idea was suddenly born. I know it's really short but, hey, whatever.

This wasn't his first kiss that would be on television, but it was his first with her. Matt had always had a certain fondness for Alex, what with all of the constant flirting, but lately he's felt this... fondness, more than usual. All throughout his break, he worried about what would happen. Would he blush and she would laugh at him? What if she thought he was a bad kisser? He was interrupted by Steven calling everyone back to the set. Time for the first take.

"What, that's it?" Matt can hear his heartbeat in his ears and gulps, looking down at his shoes. "What's the matter with you?" He turns around trying to look completely unaware as he possible can, still trying to be as smooth as he can while still in character.

"Have I forgotten something?" His heartbeat is louder now, and he's sure Alex can hear it, too. But she only smiles, still in character.

"Oh," The more Alex leans in, the louder his heart is, "Shut up." He leans on the gate of the cell, then it happens. Their lips are almost touching when he laughs.

"What, was it something I did?" Alex says, also laughing now.

"No, no."

They are ready to do the scene again, after the makeup crew comes to fix their hair and Alex's lipstick. Matt's nerves have calmed a bit by the time he walks from the TARDIS. They're back in the same position as last take, this time Alex is leaning on the gate and Matt is standing in front of her.

"Oh, shut up." Their lips meet, his heart louder than ever. The thoughts from lunch are back, as well as a few new ones, to taunt him. He rest's his hand on her shoulder and grabs the gate with his other free hand instead of simply standing there awkwardly with his hands at his sides. Alex's hand rests on his arm. Then, Matt was sure he could hear a bit of laughter over his heartbeat and menacing thoughts, but chooses to ignore it, telling himself that he's imagining things. He knows he's not imagining things when Alex squeezes his arm and shaking him a bit. He pulls away and opens his eyes to see the entire crew laughing, including Karen and Arthur who had chosen to stay for 'the main event', as they were calling it. Alex is laughing, too, but not mockingly, instead she hugs him, resting her head on his chest and rubs his back.

Later on, after 3 more takes, Alex and Matt decide to watch the footage of all of the takes. The second was the one in which Matt had messed up a bit. He completely ignored Steven yelling cut, the crew yelling cut, even when Karen yelled cut jokingly. They both stood in front of the monitor laughing, Alex rubbing Matt's arm as his cheeks turned red.

"Well, if I didn't enjoy it, I would have complained." Alex said, winking and then laughed at the deeper shade of red that appeared on Matt's face. She squeezed his shoulder and walked away to talk to Steven about her next scene.

"You like her, don't you?" Karen elbowed him, taking him away from his thoughts about Alex. "You like Alex, don't you?"

"No, of course not." He directs his gaze back to Alex, standing next to Steven nodding her head and laughing, her curls bouncing. "Of course not."
