Disclaimer: I do not own Criminal Minds

It's late in the evening; she's wondering what clothes to wear.
She puts on her make-up and brushes her long blonde hair.
And then she asks me, "Do I look all right?"
And I say, "Yes, you look wonderful tonight."

'It's not too much?' Penelope asked as she twirled around, the emerald skirt of the dress flying out elegantly as she went, wrapping around her thighs and settling back in place as she stopped; her grin full of nerves.

Derek sat staring, his mouth almost slacked enough to be gawping at how beautiful she looked right now. 'Never too much... you look wonder.' He kissed her head. 'Perfect even.' He kissed her forehead and left the room, the area feeling tighter, the air feeling low of succulent oxygen levels, his mind holding the mental images of her as she stood in front of him.

'How late are we?'

'Not late... it'll be fine.'

'It starts at 8 handsome, it's now 7:45... how long does it take to get there?'

'Look my sister is not going to worry if we are a couple of minutes late.'

'It's a rehearsal for her wedding... how will she not worry?'

'I've rung ahead. My mom's got it under control.' She looked at him with disbelief. 'If you stand around anymore we are going to be really late.'

'I'm coming.' She said and walked past him and out of the door into the Chicago night air, he followed her seductive swagger, her perfume filling his senses, his mind continually boggled.

We go to a party and everyone turns to see
This beautiful lady that's walking around with me.
And then she asks me, "Do you feel all right?"
And I say, "Yes, I feel wonderful tonight."

'You done this before?' Derek asked as he and Penelope danced to the slow music, him keeping her frame perfect, their bodies close.

'Been to a wedding rehearsal? Yes, who hasn't?' Penelope replied keeping up appearances.

'True I suppose. You're just so perfect you know that?'

'How much have you drunk?'

'Hardly any yet but as soon as we walked in everyone looked at you draped on my arm... I liked it.'

'Well sugar pants you ever need this again, I'll save your sweet arse.' She said with a smile. 'I need to sit down, my feet are killing me.' She said and broke their embrace, leaving him there; he followed her slowly and sat back at his place. 'You okay?'

'Yeah.'

'Sure? Because you don't look okay?' She asked placing a hand on his, squeezing it gently.

'Little sister's getting married, little too much.' He said with a half smile, a thoughtful smile. 'I'm going to get some air. You be okay here?'

'Yeah I'll be fine.' Penelope told him and watched him leave.

I feel wonderful because I see
The love light in your eyes.
And the wonder of it all
Is that you just don't realize how much I love you.

Derek stood outside, he had drunk too much, and it wasn't helping him clear his mind. It was like the thoughts were glued in place as the champagne washed through his system. Even the air didn't help, it made the hangover come over quickly, made him feel the pulse in his head.

How had Penelope fallen for the trick that he hardly drunk anything? Easy, she'd sat on the sidelines while he had stood and chatted to people from his past, women from his past. He ran a hand over his head.

Penelope had come with him, looking wonderful, her eyes a light wire of lust, her smoky eye shadow emphasising her brown irises as they smiled at him. As the mental image of those eyes came into his mind, he realised he loved staring at them, loved watching her ruby lips move with each sensual linguistic word that slipped through when she spoke.

Alcohol wasn't fuelling his thoughts as he went back inside.

It's time to go home now and I've got an aching head,
So I give her the car keys and she helps me to bed.
And then I tell her, as I turn out the light,
I say, "My darling, you were wonderful tonight.
Oh my darling, you were wonderful tonight."

'Give me your keys.' Penelope said as he sat down, Derek looked at her. 'You're completely sloshed angel fish so hand erm over.'

Derek handed over them over and stood and approached his mom. 'If you want me on top form tomorrow, I'm going to need to get to bed.'

'Okay son, you did good tonight.' Fran said hugging her son and then looking at Penelope. 'Thank you Penelope, Desiree appreciates it.'

'It's nothing; I'd do it for my best friend any day.' She said looking at Derek.

'Mmhmm.' Fran said. 'Anyway, he'll realise what's under his nose ones day.'

'I'm not going to hold my breath; I'll get him home and see you tomorrow.'

'Thanks again.' Fran said again and hugged Penelope.

'No problems Fran.' Penelope said and turned to look at Derek who once again had the thoughtful glaze to his eyes. 'Come on handsome, let's get you home.'

Once they were in Penelope pushed Derek into his room, he turned and pulled her into his arms, snaking them around her, his lips pressed to her hair. 'Thank you for tonight baby girl, I really love you for it.'

'You needed a date last minute, I was free, of course I'd help.' Penelope smiled at him. 'Now in you get, big day tomorrow.' He slid his clothes off, right down to his boxers and climbed under the sheets on his bed. Penelope quickly grabbed his clothes and some hangers and began to leave.

'You really did look wonderful tonight sweetness... truly beautiful.'

'Go to sleep Morgan.' She whispered and he could hear the smile in her voice, like always. 'See you in the morning... I'll have the aspirin ready.' She then left fully.

Come Monday she'd be back to Derek's friend, but for the weekend she'd enjoy being Derek's date.
