Pulling up to the curb of Callen's house Sam watched as his partner exited the challenger. 'You OK?' he asked concerned as the car ride was done in silence.

'Fine' replied a distracted Callen as he leaned down on the open window, looking into the car.

'You seem elsewhere'

'I'm just thinking about Nell'

'Really? Came the response as did the smirk that began to appear on the man's face, sitting in the car, along with a gleam in his eye.

'It was her first kill' defended Callen. 'Aren't you worried?'

'Yeah I am. Very worried' agreed Sam, turning serious. 'Nell over analyses everything. And if she over analysis's this too much she could go to a very dark place'

'Yeah' agreed Callen with a sigh. That's what I'm afraid of' he thought. 'Pick me up in the morning?' he asked as he stood up.

'Yeah' answered Sam. 'Night'

OoOoOoOoOoO

As Callen walked the path to his front door he flipped and turned his cell phone in his hand, thinking.

Kensi and Deeks had taken Nell home.

If Kensi had felt that the woman needed support she would have stayed with Nell. If Nell had told both Kensi and Deeks to leave because she was 'fine' one of them would have called Callen.

Callen sighed. He was team leader. He needed to make sure his team was OK. It was his job. Nell was part of his team.
He dialed Nell's cell and held his own to his ear, listening to the phone ring. 'Nell. It's Callen, just checking to make sure your OK' he said as the phone went to message back.

OoOoOoOoOoOoO

Before Callen had a chance to sit down and settle himself at his desk the following morning Eric Beal had run down the stairs from OPS and was standing in front of the lead Agents desk 'Have you heard from Nell?' he asked rocking back and forward on the balls of his feet.

'No. Is she not upstairs?'

'I'm worried. She hasn't answered any of my calls and that's not like her'

Callen nodded in understanding, Nell not answering calls was very unlike her. 'I'll go see her'

'Thank you'

OoOoOoOoOoO

Hearing knocking on her apartment door Nell got up from where she was sitting and walked towards it. Looking through the peep hole she found Special Agent G. Callen on the other side.
If the events of the previous day took place months ago she would have opened the door straight away. But she wouldn't.

'Nell' she heard Callen call. 'It's Call...G' Callen waited, but the door didn't open.
'I just came round to make sure your OK. Eric's worried. I'm worried. He thought.

As Nell moved away from the door, Callen on the other side rubbed his hand over his head in frustration 'Nell'.
Realizing that she wasn't going to open the door, Callen stepped back from the door, turned and walked back down the hall.

Sitting in his car outside Nell's apartment building, Callen dialed a phone number and held his cell to his ear.
'I need your help' he said as the person on the other end picked up.
