Donna gives up, and Toby comes up with details for Josh about Galileo's mission, and how everything was on target up to the point where it was supposed to release two probes, firing them deep into the ground in the search for water. This didn't happen. Josh asks, "We think if we hit the ground hard enough, we can make it to the centre of the planet and find water?" Toby says yeah. Josh asks, "That's not a theory of physics pretty much disproved by Wile E. Coyote?" The probes were supposed to send a signal back to Earth but it hasn't happened. It entered a communications blackout period and hasn't been heard from since. Toby adds, "I know how it feels." Toby says they're trying whatever things they try in these situations and that he's going to give it an hour and then tell Leo they have to cancel the classroom. Donna calls to Josh from outside his office about the stamp. Josh looks weary and tells Toby that he was supposed to do this. Toby says, "I delegated it." Toby leaves as Donna strides into Josh's office, saying that she has more index cards. We're left to imagine the look of sheer delight on Josh's face.
