Arthur Abandons sick!Merlin reveal fic

[Max Magnality]

I read something a while back where Merlin is at death's door (due to illness, I think, but I don't quite recall) and summons the blue orb in his semi-conscious state, much to the shock of Arthur who hasn't left his side. After a brief explanation from poor Gaius, Arthur announces that, "He will be buried with no honours. Tell me when passes." and sweeps out of the room in full douche mode only to return full of remorse later when Merlin takes a turn for the worse.
Please and thank you to anyone who can point me in the right direction!💕
