Abraham is a minor character in season 1 of Sense8. Abraham is a jewish diamond merchant. Wolfgang and Felix meet with Abraham to sell their stolen diamonds.
On inspecting the diamonds, Abraham says that he thinks he knows where the diamonds came from. He recommends that they be recut, making them easier to sell but worth a fraction of their value. Wolfgang refuses, and Abraham agrees to purchase half.
Later, Abraham contacts Felix and agrees to purchase the remaining diamonds. However, Abraham misses the appointment, and Felix finds that Abraham's shop has been suddenly closed. The same day, Felix is shot by Steiner.
Abraham's current whereabouts are unknown. It is likely that he was either assaulted or killed by Steiner and his men.
