Which is pretty much what the message of the episode was. The entire episode says, "Iris is not to blame, Doryuuzu was freaking out and misunderstood his trainer caring and encouraging him as her not caring (the details of how he could have made that mistakes are actually felt very forced and weren't believable). What Iris is saying is almost verbatim that. She's saying that Doryuuzu felt he couldn't win, yet she didn't stop encouraging and believing in him, and then she admits... what exactly? "Sorry it didn't cross my mind that encouraging and caring for you, telling you I believe in you, would make me come across as a careless bitch" Which then in turn makes Doryuuzu realize he was wrong... and then both act exactly as Iris says they should have acted from the start.
