Forgive me it's been quite a while! Got distracted but will finish this story I promise. Sorry guys!

'Warehouses?' Hetty queries as she finally re-emerges into Ops afraid Gibbs is being injured by Melissa. Hetty was aware Melissa's emotions were particularly raw. The case is personal and although she is the consummate professional, the pressure was starting to show. Callen is right behind her, his face giving nothing away. Nell and Eric are behind them and quick to go back to their work station careful not to get involved.

'Warehouses.' Gibbs repeats for the new arrivals.

'Nell can you pull up warehouses on the big screen within a 10 block radius of the attack?' Melissa requests. Nell does as she asks without question.

'Why warehouses?' Callen interrupts.

'Mr Callen, a very valid question.' Hetty observes.

'He prefers open spaces, our old hangout was a warehouse.' Melissa replies absently and Gibbs nods.

'Dante Davies. His first attack was at an abandoned warehouse, the murder of Kyle Davies. It's become his MO. He knows Melissa will search for him there, in warehouses as a result. Every time they've been pitted up it's ended in warehouse.' Gibbs explains to both Hetty and Callen. Hetty simply nods as she looks over to Melissa who is looking at the map that she had spread across the table. She tries to judge what is going on in the younger woman's head but is failing. Her expression gives nothing away. There's simply a look of determination and a certain ignorance to what is going on around her.

'It's not the first time you two have dealt with this guy?' Callen asks looking at Gibbs. Melissa is still concentrating on the map in front of her, trying to block out their discussion, determined to narrow her search down.

'He was Melissa's first case with NCIS. I've only dealt with him once. Melissa has dealt with him more than I have. We put him away but he's crazy, he still thinks there is hope for him. They were friends before he lost the plot and killed his twin brother.'

'That's rough.' Callen managed.

'Rough doesn't cover it Agent Callen.' Melissa stated as she finally looked up from the map. 'It is what it is.'

'It is what it is?' Callen asks staring her down. He's unamused by the steel in her voice, unused to her being defensive and closed off. Hetty folds her arms next to him but does not intervene. Gibbs takes a step back.

'We are both two very different people now. I'm not that girl and he is no longer the guy I thought I knew. Now can you stop asking pointless questions?'

'It is not pointless.'

'It is unless we catch him. I count dozens of potential warehouses that he could be hiding out,' She points at the map. 'He is going to attack someone else if I don't work out which one soon. He will keep hurt people until he knows he has my attention so the quicker I do the less chance of an innocent getting hurt! Do you get that?'

'I get it!' Callen snaps

'Well stop making pointless observations and help me catch the psycho then.'

'What about that one?' Callen points to a warehouse on the map.

'Too small.'

'That one?' Gibbs tries pointing to the warehouse a few blocks away.

'Street's too busy LAPD canvass that street once a day, drug route, too high risk.' Melissa shakes her head as she explains.

'Best place to hide is in plain sight, he wants you to find him.' Gibbs retorts.

'I know Jethro!'

'OK…'

'Sorry… Nell can you narrow the parameters to warehouses bigger than 3,000 square feet?' Melissa finally looks back at Nell and Eric.

'Sure.'

'We have 6 possibles.'

'That narrows it down…' Callen remarks as Sam joins them in Ops.

'What narrows it down?' Sam asks.
