Dylan Keogh. The grumpy, maverick medic.

Sam Nicholls. The young, pretty student doctor.

Two people who weren't meant to be together.

It went against all of the rules, but they didn't care.

They thought they were in love.

They thought that nothing would ever break them apart.

Something did, though.

An affair.

In the army.

She left, and he moved on.

Neither of them cared, they just ignored the fact that they once made a pact.

They were married.

He went to Holby, and didn't let anyone get in his way.

That was until she had to go and ruin it.

Everybody was puzzled – how did they know each other?

But then it all came out.

During a fire.

She thought he was going to die, so she told them.

He was angry, and refused to sign the divorce papers.

She protected him from an angry patient and broke his neck.

They kissed at the GMC hearing, and he thought they were getting back together.

But she had moved on, so reluctantly, he signed the papers.

But it killed him to watch her flirt with another man.

So he left.

She didn't want him to, but he did.

Breaking her heart like she broke his.

Gone.
