1 Who became a knight in this season?
Answer: Mordred

Arthur and Merlin were reunited with Mordred after many years. After Mordred stabbed Morgana, thus saving Arthur's life, Arthur decided to repay him by making him a knight of Camelot. Merlin was wary of this because of a prophecy that a druid would be the cause of Arthur's death.
When this prophecy was first mentioned (in the episode "The Beginning of the End", Mordred's debut appearance), the Great Dragon explicitly stated Mordred would be Arthur's downfall but now it was changed to an unknown druid.

2 Listed below are the fates of people according to Arthurian mythology. Which one is identical to their fate in "Merlin"?
Answer: Arthur - stabbed by Mordred in the Battle of Camlann

Like in the legends, Arthur was stabbed by Mordred (and vice versa) in the Battle of Camlann. Merlin then took Arthur to Avalon where he would remain until the land of Albion needed him.
Merlin survived the series and even lasted into the present day, still waiting for Arthur to return.
Guinevere did cheat on Arthur with Lancelot, but the two of them made up. She continued to rule as queen of Camelot even after Arthur died.
Uther was stabbed and while Merlin (disguised as an old man, since he had to use magic but it was banned in Camelot) tried to help, he just made things worse. Because of the help of Morgana and Agravaine, Uther died.
Morgana's fate was also different. She survived the events of Arthurian mythology. However, in the series, she died at the hands of Merlin.
    Your options: [ Uther - drank water that was poisoned by Saxons ] [ Merlin - died in a cave thanks to the Lady of the Lake ] [ Arthur - stabbed by Mordred in the Battle of Camlann ] [ Guinevere - became a nun after her affair with Lancelot ]
