The Ultimate 4.5 "The Constant" Quiz | 'Lost' - Seasons and Episodes

Answer: Charlotte

Charlotte is still on the island. Frank is transporting Sayid and Desmond to the freighter. Due to weather conditions, Frank is unable to maintain the prescribed course and surprising side effects ensue.

Answer: Baghdad

Sayid wants to call the island, in order to assure them that he is alright. As Frank hands Sayid the phone, he says, "Be quick. And don't go trying to call Baghdad, those phones can only call each other." Ignoring this bit of sarcastic humor, Sayid proceeds to contact Jack on the island.

Answer: He is a soldier in the Royal Scottish Regiment.

We see Desmond shift from the present to 1996 with increasing frequency. Desmond is causing problems for the other soldiers in the regiment because of his seemingly unstable behavior.

Answer: Eloise

Daniel instructs Desmond to travel to the Queen's College Physics Department at Oxford University. Desmond must first give Daniel some specific device settings. If that fails to convince Daniel, then Desmond must tell him that he knows about Eloise. Daniel has been performing time experiments on a rat named Eloise.

Answer: Minkowski

Here, we finally get to meet the mysterious George Minkowski, the communications officer. Minkowski is experiencing the same side effects as Desmond. Minkowski recognizes Desmond's name from phone calls to the ship from the mainland.

Answer: Penny

Daniel suggests that Desmond must find an anchor, or something familiar in both times, to prevent the increasing oscillation between times. Daniel refers to this as his "constant." Desmond immediately tries to make contact with Penny, however her phone has been disconnected.

Answer: ship's journal

Mr. Widmore wins the bidding for lot number 2342. The item is a journal authored by the first mate of the Black Rock. The Black Rock was a British trading vessel, the wreckage of which, can be found on the island.

Answer: Tovard Hanso

Tovard Hanso is the owner of the ship's journal being sold at the auction. It is stated at the auction that only members of the Hanso family are familiar with the contents of the journal.

Answer: Yes

Sayid and Desmond unstrap Minkowski and he guides them to the ship's communications center. Unfortunately, Minkowski succumbs to the effects of the time shifting and collapses. Desmond finds Penny back in 1996 and pleads with her to give him the number. Reluctantly, she tells him the number provided that he leaves.

He promises to call her eight years later. Sayid repairs the line and Desmond makes his phone call to Penny. Penny answers and they profess their love for each other. Desmond has thus, established his constant and his memory is fully restored.

Answer: Desmond

Well aware of the island's strange temporal effects, Daniel has planned ahead. In his journal, Daniel has written, "If anything goes wrong, Desmond Hume will be my constant."
