Sergeant Defoe was watching the blonde nurse struggling to cut the cable ties holding the access door closed. The poor woman was clearly under the influence of drugs and was having a problem concentrating. She was also trying to cut the ties with nail scissors with limited success. He was encouraging her to stay focused and she smiled at him, before frowning in as she snipped at the ties.

Suddenly there was a gunshot.

Defoe grabbed his radio.

"Shot fired, shot fired!" he called.

He posed ready to throw himself at the door in the hope that the nurse had done enough damage to the cable ties.

The chief's voice came on the radio.

"Hold you position." he ordered.

"Understood." said Defoe, trying to push down the urge to charge in guns blazing. He knew all too well going in with a hot head is what gets people killed. The chief was right they still had the element of surprise and they still didn't have all the facts.

Defoe turned his attention back to the nurse in the corridor.

She had dropped to the floor at the sound of the shot but she was now furiously pulling at the cable ties in desperation; her eyes haunted; her mind probably elsewhere.

"Give me an update." ordered the chief's voice over the radio.

Worried that the young woman would do herself an injury in her current state Defoe nodded to the Gamma team leader to report back while he tried to draw back the young woman's attention and help her calm down.

When she noticed him again she blinked.

She mouthed two words, but it was hard to hear her through the thick glass, it looked a little like she was saying 'mushroom man'. Defoe smiled at her and made the scissor hand signal to her like he had before.

She frowned at that for a moment as if she had forgotten what she had been doing, but then she noticed the nail scissor's on the floor.

She picked them up and after some more pointing and smiles of encouragement; she began snipping at the ties again.

That poor girl was still really out of it, but Defoe knew she was their only quiet way in and after that gun shot, they really needed to get in.
