"Let the penalty be named as exactly one pound of your fair flesh"
Later on, We learn from Salarino and Solanio that the many investment that Antonio made were found shipwrecked. They get in a heated argument with Shylock over if he would really enforce his bond. He proclaim that he would
Shylock learns of Antonio misfortune from his friend Tubal, telling Tubal to get a officer to catch Antonio
We skip to the scene where Bassanio and Shylock are conversing, Shylock obviously displeased that the Jailor would let Antonio outside at his request

I'll have my bond; speak not against my bond
I am sure the Duke will never grant this forfeiture to hold
