I think Plagg physically can't tell Adrien the truth because Gabriel wielded Monarch at some point, and he doesn't know about the sentimonster stuff.
Yeaah, I know cuz of the goofy "black bubbles nonsense " he can't say Gabriel's name fr and I figured he didn't but it makes more sense if Plagg at least TRIED to tell him (about the Gabriel thing, unfortunately ig no one's gonna tell him hes a sentimonster)
Also I'd attempt to figure out a way around that 'cant say a holders name' thing cuz this show can't be consistent on its lore anyways 💀
