The team finds that Maxwell's phone is on a group of dead people on a plane killed with, you guessed it, poison.

As a result, there's many questions about where he is.

But the team finds him at a hotel bar and he reveals he has a detonator.

His name is Jason.

When Tennant reveals this, he reveals he's going to blow things up in Hawaii.

However, the plan works and Torres and Tennant fight back to save the city.
