Gaius needs to go.

Nah for me Lancelot needs to go. I really wanted to like him but couldn't...

I only ever saw Lancelot as an obstacle.

Ever since Goblin's Gold in season 3 I've forever loved Gaius!

For me Elyan needs to go . I like Lancelot, Gaius and especcially Mordred <DD

Exactly Kim, if they utilised him and gave him better story lines away from Gwen and Arthur I would have liked him more.

Elyan hands down! I can't stand him! After Agravain and Uther, he is the worst. Family should be everything. He was the worst brother ever! I will never forget that throne room scene.

Oh and I love Mordred and Lancelot.

Elyan died saving Gwen... I think that screams best brother ever!

Lancelot and Elyan... Elyan was the worst brother ever!! And Lancelot was supposed to be one of Camelot' finest knights and he wasn't. He portrayed as a weak man who is ,let's say, in love with Gwen. And he didn't even try to fight for his love.. That is no knight. That is a coward.

Elyan died saving Gwen so he forever holds a place in my heart. I liked his character and I wish he was used more.
I loved and respected Gaius, I think there was so much more they could've done with his character based on his experiences and him being one of the only people old enough and close enough to Uther to see a large portion of the initial Great Purge and I respect Gaius' perserverance and faith in Merlin and Arthur.
Mordred has so many layers and despite the fact that he ended up fulfilling his dark destiny he still intrigued me and I wish we got to know more of his backstory and experiences. It was hinted that some people knew about his gifts and wanted to use him (besides Alvaar) but not much else.
For Lancelot... I don't hate him. I ship Arwen so I suppose it's expected of me to hate him but I don't. I think he was a good friend to Merlin, an honest man and a good person and it's sad how Morgana destroyed his character but if I absolutely had to choose... Mordred.
