Merlin: Why do you want to do this?
Gwaine: Same reason as you. Help a friend. Merlin: Arthur's lucky to have us.
Gwaine: Not Arthur.
Merlin: I'd do the same for you.
Gwaine: I hope so. You're the only friend I've got.
Merlin: I'm not surprised.
I don't mind Gwaine's funny remarks or his comic relief scenes (some are funny indeed and Eoin is great at delivering one-liners) but I don't like that we didn't get to see much of the Merlin/Gwaine friendship after series 3.
