Forgiveness part 2

A story..... (with apologies to Matt 18:23-28)

Once there was a king who decided to check on his servants' accounts. He had just begun to do so when one of tem was brought in who owed him millions of pounds. The servant did not have enough to pay his debt, so the king ordered him to be sold as a slave, with his wife and children and all that he had, in order to pay the debt. The servant fell on his knees before the king. 'Be patient with me,' he begged, 'and I will pay you everything!'. The king felt sorry for him, so he forgave him the debt and let him go.
Then this man went out and met one of his fellow-servants who owed him a few pounds. 'Pay me back what you owe me,' he said.
But the other servant said 'I have no idea what you're talking about. I don't owe you anything. I don't need to make any kind of restitution to you, because there's no reason to. If you think there is, you're mistaken and it's your problem, not mine.'

so what happens next?
does the forgiven servant forgive?
do they demand justice?
do they just give up, as they're obviously not going to get anywhere, so what's the point?
