By the time Mack and Melinda arrive, Eli has left the building and let a wall of carbon behind him to deter pursuit.

Melinda doesn't believe it and neither do the others, and Daisy says that they have to let Jemma know so she can solve it.

Jeffrey says that they'll follow the leads once they study the tech, and tells him to prep the dead tac team agents. He and Melinda will go on ahead in the Quinjet, and Radcliffe will examine the cargo. When Melinda wonders if Jemma approved it, Jeffrey claims that they talked to her but they'll proceed while she returns in a few hours.
