My honest opinion is that they completely ****ed up Season 2 because how do you guys end Season 1 with him being able to completely control his powers plus his twin brother also acquiring his demonic powers also to Rin not controlling his powers but his mentor exposes her true self when in season 1 nobody knew about her at all until the first fight she protected Rin so season 2 should've been a spin off and continued the story of the two brothers being Demonic Exorcists or they should've started off season 2 with Rin's brother learning to accept and control his powers not him not even knowing he has the powers in the first place
