Arthur/Artura Pendragon
Kay and Arthur/Artura were raised together by Sir Ector, and when Arthur/Artura came to Camelot, he was the one who made sure the castle was liveable. In the Chapter 2 flashback scene, a younger Kay and a younger Arthur/Artura are in London. He/She used to be Kay's squire, and when Kay forgot to take his sword to the tourney, Arthur/Artura was charged with finding him a new one. However, Arthur/Artura found Excalibur instead, and wielded it himself/herself. A premium Chapter 4 scene reveals that Arthur/Artura and him played hide-and-seek when they were younger. Chapter 8 reveals that in their youth, they modified a recipe that Sir Ector created. If you keep watch with Arthur/Artura and state that Kay must have been worried about him/her, he/she tells that the two of them used to sneak out to the woods and later tells that Kay has felt a responsibility from the time he/she became king/queen.

Sir Ector
In the mentioned flashback, Sir Ector gives Kay advice on how to fight in the tourney.

Gawain
While in the cellar during the premium party grail scene, Kay tells that he challenged Gawain to arm wrestling to avoid hearing about Gawain's experience with the Green Knight. Some time after that match, the Knights of the Round Table spent about an hour arm wrestling each other. Someone else besides Gawain won the final match.
