In Star Trek: Discovery Season 3, Episode 5, the USS Discovery and its crew finally locate and reach Federation and Starfleet headquarters thanks to Adira gathering the location from Senna Tal's memories. These separate entities must now abide together. Burnham, Saru, and Adira are summoned to meet Starfleet's Commander in Chief, Admiral Charles Vance (Oded Fehr). The Discovery crew are anxious to help the Federation, but Vance says a debrief must come first.
Meanwhile, Sick Bay is overflowing with Kili refugees, who have been affected by prions and have 4 hours to live. They need an antidote, which requires travel to the USS Tikhov that is 5 months away. Only the Discovery and its spore drive can help get there and back in time. Chastity and Greg recap the story and comb through Episode 5 for Easter eggs and Star Trek references from past episodes of Star Trek Voyager, Deep Space Nine, TOS and TNG.
