One step killed two men

Three years killed four more

As Five days turned to six

Seven sins would turn to eight

Nine drinks would turn to ten

And he wondered if he'd ever see Sherlock again

One day at two after noon

Three years since his heart split to four

Five knocks led to six

Seven steps was eight too much

After number nine he let Ten in

The Doctor would help let the search begin

One hour later showed two more

The past three years examined the four

At five the brothers proved him alive

At six Ten promised the Fall he'd fix

The brothers bickered from seven to eight

At far after nine stepped in Ten

But by then Dean and Sam had formed a plan

One Doctor with the help of two brothers

Three years late the four remet at last

For five hours a tale was told

At half past six, they were told of the fix

Seven drinks later the eight had forgotten

The nine months of hell it took the brothers and Ten

To fight and bring them together again

One more day after two

The three that helped: The brothers and Who

Parted on four wheels at half past five

Not to mention a box bigger on the inside

The Doctor left at six, knowing nothing to fix

By seven to eight John's heart was set straight

After nine he knew he could always call the brothers and Ten

If Sherlock were to leave him again.

One kiss between two

Turned to three and then four

Leaving five fingers grasping for more

Six became eager and seven turned to passion

After eight led to nine

And nine called for ten

John never let go of Sherlock again.
