Can someone please help me

"Floating now in the air, a figure unfolded, flexing joints and stretching muscles that had not moved for decades."

Is it just me or does this imply that Agrona's REAL BODY HASN'T MOVED IN DECADES!? If that's true then He's WAYYY SICKER than any of us thought because that means that Agrona is NOT SYLVIE'S FATHER!!

Honestly, TM has officially made the most confusing plot point in the entire series so far, since if this last chapter is correct, that means AGRONA TRICKED SYLVIA INTO HAVING SEX WITH A STRANGER'S BODY!!

I guess we can add another sex offender charge to Agrona's already infinite long list of crimes smfh. My question is How TF is TM trying to convince us fan's that SYLVIA (an Asura, a being who is the MOST "in tune" with mana and even MADE of it) COULDN'T EVEN TELL THAT SHE WAS HAVING SEX WITH SOMEONE ELSE THAT WASN'T AGRONA?!? I understand if he used a spell that made him appear to be Agrona, but I don't see how you could FAKE HIS MANA CORE!

I wanna hear what yall think about all this specifically though! Am I reading it wrong because the quote I added from the last chapter LITERALLY says that Agrona's body hadn't been moved in decades! So I'm really intrested in everyone else's theories of how to explain all this nonsense away lmfao
