(So I'm gonna cut in here-first off, Siren's kingdom is actually INCREDIBLY supportive of him. They all love him unconditionally and believe that he can do it-which is why he feels so guilty and like he can't/doesn't live up to their expectations. Two: the kingdom's actually under a curse. It causes the sharks to be more susceptable to tradgedy/accident, making them sustain more and more injuries and often resulting in their deaths. So it's not really a-he can just shrug this off type of thing.)
(OHHHHHH, Oookay, let me try that again)
He swims slightly back, looking down to the ground
"Y-Yes i know....it's just, i feel like this is my fault that...everyone in my kingdom is getting injured, and all i could do is sit back here and watch! I understand that they think it's not my fault, i just....don't believe it..."
