These days I have enough thoughts and feelings about Adrien (and Gabriel Agreste and sentiadrien and everything) to write a dissertation, but art is easier
Felix: "I want to keep Sentibeings safe"
Also Felix: *doesn't tell Adrien he's a sentibeing, even though the rings are in Adrien's possession*
-------
Marinette: "I want to protect Adrien"
Also Marinette: *Breaks the rings withholding Adriens amok, knowing that could've caused Adrien's death*
I want Adrien to fake his death when he find out (on his own) that he's a senti, so that everyone who kept it a secret from him would realise they've messed up bad in giving him the rings while not telling him the real importance of them.
