Barclay's work on the Pathfinder project earns him a promotion to full lieutenant (previously he had been a lieutenant junior grade). And an honorary crewman aboard Voyager. In the episode , it is also revealed the Barclay has made a further breakthrough that uses the monthly rotation of a Cyclic Pulsar Amplifier to establish Starfleet-Voyager communication. This is very fortuitous as we learn that Lewis Zimmerman, the creator of the Doctor's Emergency Medical Hologram program, is dying and no Starfleet medical personnel can determine the reason. Next month, the Voyager's EMH Doctor is sent to Zimmerman's Laboratory using Pathfinder, and with some scheming by Barclay, Deanna and Zimmerman's holographic female servant, Haley, the Doctor cures his creator after some earlier difficulties. Weirdly in the intro Zimmerman says that this will be the "First Intergalactic Phone Call" revealing he is not aware of the previous successful contact.
