In the end, it was the easiest decision she'd ever made. Given a choice between her life and the lives of everyone she'd come to care about... Well, there was no contest as far as Melissa Createn was concerned. She sat at Nell's chair in front of the monitors, bathed in a red glow as the lights flashed around her and the klaxons blared, an automatic voice warning all personnel that they had six minutes remaining to evacuate the building. Six minutes until the security protocol attached to the lockdown programme would be initiated and the climate control systems would kick in to start removing the oxygen from the very many offices and floors of the Boatshed. There was no physical threat, no incursion. At first, they (Nell, Eric and Melissa) had thought it was a computer glitch – an error in the programme. It was only when they realised that the lockdown programme was causing the doors to shut far too fast to be normal that Melissa realised it was a virus that had been planted in the system. The others were being evacuated; they'd had no choice but to temporarily abandon the building. Eric had already left with Hetty, Granger and the Ops team, a laptop hooked up remotely to the system in his hands. Kensi, Deeks and Sam were overseeing the evacuation process, making sure each level was secured and that all personnel were accounted but one, but they wouldn't realise that until it was too late to change it.
