Had this crazy idea of Callen sort of having an unknown valentine.I plan on expanding on this. Any prompts welcomed. Planning on keeping this going up to ten chapters if I can.

I enter the bullpen at 6:45 a full fifteen minutes later than usual. Sam is parking the car. I walk in and Kensi and Deeks are in already. Melissa has her head in a file as Deeks and Kensi blatantly flirt in front of her. Deeks is drinking from his superman cup that Kensi gave him for Christmas unaware that we all know the hidden meaning… That he stayed over hers last night. I put my bag down and notice a box on my desk as I do. It's red and from the window in the top I see a cupcake with blue icing on it and a yellow star. Melissa smiles as they both hug and I notice the sparkle in her eyes as they do. I sit down and look at the box. There's a note on the side, taped on, but it's typed. There's no clue as to who has sent me this cupcake. That frustrates me. I want to know who sent it….

'So did you get a cupcake or is the box empty?' Deeks enquires as he sits down at his desk.

'No I got a cupcake. Who was first in?' I answer with a question looking at my colleagues.

'I was.' Melissa responds by looking up with those sky blue eyes of hers. 'It was there when I got here.'

'It wasn't here last night.' Deeks immediately comes to take a look.

'I don't believe it was.' She answers before looking back down as Sam enters. Sam notices the box too and immediately walks over to investigate it further. He looks into the box and then carefully removes the note. He nods.

'Question mark? What sort of message is that?' Sam jokes as he passes me the typed note with a smirk.

'A very vague one,' I counter quickly as Sam and Deeks return to their desks.

'It seems you got an admirer G.' Sam teases in his usual tone towards me as he sits.

'Sam do you know anything about this?' I coax. I notice Melissa is being quiet. Kensi is too but she seems intrigued by the mystery.

'Why would Sam know anything?' Melissa pipes up and I face her surprised at the tone in her voice. There is something new in it, something different almost mocking.

'I'm simply asking if he has any suspicions as to the person behind the appearance of this cupcake on my desk on Valentine's day.' I remark noticing the expression on her face change from teasing to serious.

'If he does Callen I'm sure he would tell you or even question the person he suspects….' She pauses before smiling once more. 'Why don't you ask Hetty she knows everything?'

'Maybe I will…'

'Maybe you should….' She says simply putting her pen down and leaning forward and staring me down playfully. Something is definitely different with her today.

Deeks, Kensi and Sam are all watching the exchange. Sam is leaning back in his chair clearly interested in what we are saying, taking in each of our responses and forming conclusions in his head. Deeks is smirking as usual and Kensi is also watching keenly. Melissa picks up her pen once more and I push the box to one side. Melissa is hiding something and I'm determined to find out what. God I sound paranoid! She's the only one who seems to be not surprised by the cupcake, she's being super smart in her responses and I'm finding it hard to read her today. I look at her for a moment and I wonder to myself how much do I actually know about Melissa Louise Createn?
