Terrorist Ari Haswari (Rudolf Martin) was hiding in a body bag and held Ducky, his assistant Gerald Jackson (Pancho Demmings) and Todd hostage.
He was working with the terrorist Gibbs had killed and wanted to get the blood sample back.
In order to try and help her team, Abby goes down to the lab and, with Gibbs’ help, they are able to stop Ari.
At the end of the episode, Abby proves she is over her fear by sleeping on one of the autopsy tables.
