Mac was in the lab, working on fingerprints. Mac reached out to turn on the plug socket. Sparks flew and Mac felt a biting, burning pain shoot through his body. He screamed in pain and collapsed.

"Mac!" Jo shouted as Mac dropped to the floor.

Jo is at Mac's side in an instant. Turning him onto his back, fingers to throat and eyes to neck. One quick glance and Jo can already see; no rise of the chest, and no inhale or exhale from the lips - Mac's not breathing. A lab technician was on his cell calling 911 as he saw the commotion.

Moving with calm she did not feel, Jo tilted Mac's head back and exhaled two long breaths, lips sealed over lips. Now, fingers tangled, she twisted across to face Mac's chest. Levering herself high up onto her knees she then leant all her strength onto Mac's sternum, applying quick, heavy pressure to ribs and counting out loud: terrified of missing a beat. She returned, pinched Mac's nose closed, and exhaled again, twice.

She switched back to chest compressions; concentration solely on counting and praying. After a few rounds of each, Jo pulled back from Mac's lips and stared at the inanimate face, irrational anger building in her body. Anger at Mac, beautiful, amazing bloody wonderful Mac who was just lying there, and dying on her - just when she needs him most. Just when she - and Jo can feel her heart break, the first crack that released the damn, the tirade of emotion this is flaying in her. Damn it if Mac is dying now, before Jo even got the chanceā€¦

no god damn it please! I love you, don't leave me!

Jo leaning forward again, inhale/exhale/chest compressions, but with so much more worth behind them before, full of emotion, love, longing. Eyes blinded by unshed tears, profanity uttered under her breath, hoping, praying.

Mac!

And she missed the flicker of eyelids; the breathy inhales from Mac as he sucked back in air and began to return to hazy consciousness, but then Jo had switched and leant down to press her open lips solidly against the older man's. Startled, Mac widened his eyes but could only see the unfocused outline of the one he loved Jo, his Jo. Mac coughed and gasped. Jo jumped back in surprise. She was over the moon with happiness

"Mac, Are you okay?" She asked.

"Y-yes, Thank you," Mac stammered.

Mac smiled as he looked at his friend, she had just saved his life.
