Arthur: I don’t have friends, I can’t afford to as crown prince. As for trust, I of course have complete faith in my knights. Thats all. Nobody else. Nope.
Merlin: Probably himself, the egotistical prat.
Morgana: Merlin, though Arthur won’t ever admit it.
Gwen: Merlin.
Leon: Merlin, who is well deserved of Arthur’s trust.
Gwaine: Merlin.
Elyan, Percival and Lancelot: Merlin.
Mordred: Merlin. Like, super intense friendship there, I don’t know if its healthy.
Gaius: Merlin.
Hunith: Merlin.
Camelot: Merlin.
Kilgharrah: The other half of the coin.
Morgause: Merlin.
Uther: Without a doubt that idiot serving boy. Marvin? Mertin? Merlin that’s it. Far too close for a servant but he has proven himself a loyal ally against magic.
