The Secret Sharer As In The Person Who Shares Secretly.

This made me LOL, and put my word nerd hat on to briefly mourn the death of the hyphenated compound noun.

I was going to post about Agravaine and his box of magic nicknaks. Are we supposed to believe he has magic and that's why he's allied with Morgana, or was it - as you said - a handy way to frame pretty much anyone in Camelot any time he wants? So many questions about him rn.
